Concord grape pie

The slip-skin technique and the deep purple taste of the American autumn

Origin: Finger Lakes, New York, USA

From the journey of Grapes.

Ephraim Wales Bull developed the Concord grape in 1849 in Concord, Massachusetts, from a wild Vitis labrusca vine growing near his home, breeding a grape hardy enough to survive New England winters, productive enough for commercial cultivation, and distinctive enough in flavour to be immediately recognisable. Bull introduced the Concord to the Massachusetts Horticultural Society in 1853, where it won immediate acclaim. It is the most American of grapes: native to the Northeast, deeply cold-hardy, and possessed of the intensely musky, perfumed quality that Americans call 'grapey': a flavour profile so specific to Vitis labrusca that it appears in no European vinifera variety. Welch's grape juice (launched 1869 in Vineland, New Jersey), the peanut butter and grape jelly sandwich, and Concord grape pie all depend on this single variety. Concord grape pie is a regional speciality of the Finger Lakes region of central New York State and the Hudson Valley; areas with the climate and soil to grow Concord grapes in abundance. The pie is eaten in September and October when the grapes ripen, and it is almost entirely unknown outside these regions, which gives it the quality of a genuinely local food: not globalised, not exported, firmly rooted in a specific landscape and season. This regional specificity is part of its character; concord grape pie tastes like the northeastern American autumn in the way that a Beaujolais Nouveau tastes like the French harvest. The defining technique of Concord grape pie is the slip-skin method, which reflects the physical reality of the Concord grape: the thick, inky-purple skin separates easily from the green inner flesh; a characteristic called 'slip-skin' that is unique to Vitis labrusca varieties. The skins are popped from the flesh by hand (a satisfying, repetitive process), the flesh is cooked and strained to remove the seeds, and the skins are then cooked into the strained flesh: the skins providing the deep purple colour, the musky 'foxy' aroma, and the tannin that prevents the filling from being cloying. The filling is very liquid before baking and sets only on cooling: this frightens first-time pie makers, but the cornstarch binds the sugars and grape pectin into a perfectly sliceable filling once the pie has cooled completely. Concord grape pie is made by people who grew up in the Finger Lakes, by cooks who discovered it at county fairs and farm stands, and by those who understand that the American fruit pie tradition; which includes blueberry, cherry, peach, and blackberry; has its most regionally specific and underappreciated expression in the grape.

Ingredients

Pastry

  • 350 g plain flour
  • 200 g unsalted butter, very cold, cut into 1cm cubes
  • 1 tbsp icing sugar
  • pinch salt
  • 5 tbsp ice water, added one tablespoon at a time

Filling

  • 1200 g Concord grapes (or other slip-skin grapes), washed and stemmed
  • 150 g caster sugar (adjust to taste, Concord grapes vary in sweetness)
  • 3 tbsp cornstarch
  • 1 tbsp lemon juice
  • pinch salt
  • 1 tbsp unsalted butter, to dot over filling

Glaze

  • 1 egg, beaten with 1 tbsp milk, for egg wash

Method

  1. Make the pastry: combine flour, icing sugar, and salt in a bowl. Add the cold butter cubes and rub into the flour with your fingertips (or pulse in a food processor) until the mixture resembles coarse breadcrumbs with some pea-sized butter pieces remaining. Add ice water one tablespoon at a time, mixing just until the dough comes together. Divide into two discs, wrap in cling film, and refrigerate for at least 1 hour.
  2. Prepare the filling (the slip-skin step: hold each grape between thumb and forefinger over a bowl and squeeze gently) the inner flesh will pop out of the skin into the bowl while the skin remains in your hand. Place the skins in a separate bowl. Continue until all grapes are separated.
  3. Cook the flesh: place the grape flesh (without skins) in a saucepan over medium heat. Cook, stirring, for 5–7 minutes until the flesh completely breaks down and becomes liquid. Pass through a fine-mesh sieve, pressing firmly to extract all the juice and pulp. Discard the seeds. You should have approximately 400ml of smooth grape pulp.
  4. Combine the strained grape pulp with the grape skins, sugar, cornstarch, lemon juice, and salt in a bowl. Mix well. The filling will be very liquid; this is correct. It will set during baking and cooling.
  5. Preheat the oven to 220°C (425°F). Roll out one pastry disc on a lightly floured surface to a 30cm circle and line a 23cm pie dish. Trim the edges leaving a 2cm overhang. Refrigerate while you roll the second disc for the lid.
  6. Pour the grape filling into the pastry-lined dish (it will be quite liquid; pour it in slowly). Dot with the tablespoon of butter. Cover with the second pastry disc or a lattice. Crimp the edges firmly to seal. Cut several vents in the lid if using a solid top crust.
  7. Brush the pastry with egg wash. Bake at 220°C for 15 minutes, then reduce to 180°C (350°F) and bake for a further 30–35 minutes until the pastry is deep golden and the filling is bubbling actively through the vents.
  8. This step is critical: allow the pie to cool completely on a wire rack before slicing; at least 3 hours, preferably 4. The filling is still liquid when the pie comes out of the oven. It sets as it cools. A pie sliced while warm will be a purple mess; a pie sliced when cold will be perfectly set and sliceable.

Notes

Concord grape pie is best eaten the day it is made; the pastry is at its crispest and the filling is at its most fragrant. It keeps for 2 days at room temperature, covered loosely. Serve at room temperature with vanilla ice cream or unsweetened whipped cream. The pie can be made with other slip-skin grape varieties if Concord grapes are unavailable, but the flavour will be different. Outside the northeastern United States, Concord grapes are rarely found fresh; they are sometimes available frozen (thaw completely and drain excess liquid before using).

🌍Origin

The Caucasus region, between the Black Sea and Caspian Sea (modern-day Georgia and Armenia). — c. 8000 BCE

🌱Domestication

The grape is amongst the most consequential plants ever to pass into human cultivation, for from a single domesticated species came not only a fruit but an entire civilisation of wine, with all its attendant religion, commerce, and art. Vitis vinifera, the wine grape, was domesticated from its wild ancestor Vitis vinifera subspecies sylvestris in the South Caucasus, the mountainous country between the Black Sea and the Caspian that today forms Georgia, Armenia, and the borderlands of Azerbaijan and eastern Anatolia. The wild vine is dioecious, bearing male and female flowers on separate plants, so that only some vines set fruit; the great achievement of domestication was the selection of hermaphroditic vines that pollinate themselves and crop reliably, together with the choice of plants bearing larger, sweeter, juicier berries. Because the grapevine is propagated from cuttings, every prized variety could be cloned and carried, and the cultivars that resulted, from the pale Sultana to the dark Shiraz, were perpetuated unchanged across millennia and thousands of miles. The antiquity of the Caucasian tradition is documented in the soil itself. Archaeological sites in eastern Georgia have yielded fragments of large clay fermentation vessels, the qvevri, stained with tartaric acid, the chemical fingerprint of grape juice, alongside grape pips and pressed skins, and the chemical evidence of deliberate winemaking reaches back to around 6000 BCE, with signs of wild grape use pushing the human relationship with the vine to roughly 8000 BCE. This makes Caucasian winemaking, in all likelihood, the oldest continuously practised fermentation tradition on earth, and the qvevri method, in which whole crushed clusters are buried in earthenware to ferment slowly underground, is still followed in Georgia today, essentially unchanged across eight thousand years. V. vinifera proved extraordinarily plastic under cultivation, diverging into the many thousands of named varieties that now exist, table grapes bred for sweetness and good keeping, drying grapes for raisins and sultanas, and the great wine grapes whose names, Cabernet Sauvignon, Pinot Noir, Tempranillo, Riesling, Nebbiolo, define the fine-wine world. The fruit is unique amongst the great domesticates in the sheer breadth of its uses, for it is eaten fresh, dried into raisins, currants, and sultanas, pressed into juice, fermented into wine and distilled into brandy, boiled down without fermentation into the sweet molasses the Persians call shireh and the Turks pekmez, soured into vinegar and verjuice, and even valued for its broad, pliable leaves, which are wrapped about rice and herbs across the whole of the eastern Mediterranean. No other plant has given the human table so many distinct things from a single fruit.

Global Voyage

From its Caucasian cradle the cultivated vine spread first into the great river civilisations of the Near East. By around 3000 BCE grape growing and winemaking had reached Mesopotamia and the Nile Delta of Egypt, where viticulture became an art of the elite; Egyptian tomb paintings at Saqqara and Luxor depict the treading of grapes, the sealing of amphorae, and the labelling of wine jars with vintage, vineyard, and maker, the earliest wine-labelling system in the world. It was the Phoenicians, however, the great seafaring merchants of the Levantine coast at Tyre and Sidon, who turned the grape into a Mediterranean crop. From around 1500 BCE they carried vine cuttings, winemaking knowledge, and the Levantine habit of cooking with the vine to every port they founded, to Carthage, to Cyprus and Sardinia, to Marseille and to Cadiz, planting the seed of viticulture along the entire northern shore of Africa and the southern coast of Europe. The Greeks inherited this Phoenician inheritance and raised it into philosophy, religion, and social ritual, organising the symposium around diluted wine and making Dionysus one of the central figures of their pantheon; Greek wine, shipped in distinctive amphorae, travelled the length of the Mediterranean. Rome then transformed Greek wine culture into an imperial agricultural system, and it was the legions and colonists of Rome who carried the vine to the lands that would become its greatest homes. Roman viticulture planted the vineyards of Gaul, Hispania, the Rhine and the Moselle, and even Britain, and the agronomists Columella and Pliny the Elder documented hundreds of grape varieties and the techniques of their cultivation. The great wine regions of modern France, Spain, Germany, and Italy are, in the most direct sense, the descendants of Roman plantings. The rise of Islam after the seventh century CE recast the grape's role across a vast swathe of its range. Where the Quranic prohibition of khamr, intoxicating drink, suppressed winemaking, the grape did not vanish but was transformed into a food, and the Arab agricultural revolution carried drying and table varieties across North Africa, into Al-Andalus, and along the trans-Saharan caravan routes into the pre-Saharan oases of Morocco, where the golden raisins of the Draa Valley became a prized commodity. The grape became raisins and currants, molasses and verjuice, and the vine leaf became a cooking vessel; the Ottomans later gathered these traditions and spread the stuffed vine leaf, the dolma, across an empire that stretched from Hungary to Yemen. The final and greatest dispersal was the oceanic one of the colonial age. Spanish missionaries carried the vine to Mexico and South America and up the Pacific coast; the Dutch East India Company planted the first vines at the Cape of Good Hope within three years of founding the Cape Colony in 1652, and French Huguenot refugees reinforced the young Cape winelands in 1688. German Lutheran settlers fleeing Silesia and Prussia planted Shiraz in South Australia's Barossa Valley in the 1840s, on vines that, having escaped the phylloxera blight that devastated Europe, are amongst the oldest in the world today. French enologists introduced Malbec to the high vineyards of Mendoza in Argentina in the 1850s, and in the same decade Ephraim Wales Bull bred the hardy Concord grape from native American Vitis labrusca stock in Massachusetts, giving the United States a grape culture of its own. By the late twentieth century the vine had circled the globe, and the Judgement of Paris of 1976, in which California wines bested the grand crus of Bordeaux and Burgundy, confirmed that the grape had made new homelands wherever the climate would receive it.

🍽Modern Culinary Role

The grape stands amongst the most economically important crops in the world, cultivated on roughly 7.5 million hectares across every inhabited continent, and it is unrivalled in the diversity of the things it yields from a single fruit. It is eaten fresh as a table grape, dried into raisins, sultanas, and currants, pressed into juice, fermented into wine and distilled into brandy, grappa, pisco, and arak, boiled down into the sweet molasses of pekmez and shireh, soured into vinegar and pressed unripe into verjuice, and its broad leaves are brined and wrapped about rice and meat from Greece to Iran. Wine alone constitutes a global industry worth many hundreds of billions, and the names of grape varieties and the regions that grow them, Bordeaux and Burgundy, Rioja and the Mosel, the Barossa and Mendoza and Napa, have become a language of place and prestige understood the world over. No other fruit has generated a comparable body of cultural, religious, philosophical, and culinary literature. The grape and its wine sit at the symbolic heart of several of the world's great traditions: the Eucharist of Christianity, the Kiddush of Judaism, the ecstatic religion of the Greek Dionysus, and the legal discourse of Islam concerning the prohibition of intoxicants. In Persian poetry the grape and the cup are amongst the most enduring of all images, appearing in countless verses, most famously the Rubaiyat of Omar Khayyam, as metaphors for spiritual longing, earthly beauty, and divine mystery, and the vine is named in the Hebrew Bible more often than any other plant. In the kitchen the grape ranges from the rustic to the refined, from the harvest breads leavened with fresh must, the schiacciata all'uva of Tuscany and the mosbolletjies of the Cape, to the great wine-braised dishes of the European table, coq au vin and boeuf bourguignon, in which the fermented juice of the grape becomes not a flavouring but the very medium of the cooking. Few plants have shaped human ritual, commerce, and appetite so completely.
