Mostarda di Cremona

Lombard candied whole fruits suspended in a syrup made fierce with mustard essence

Origin: Cremona, Lombardy, Italy

From the journey of Mustard.

Italian mostarda is not mustard, and a jar of it opened in the expectation of a condiment is one of the more startling experiences in European food. What it is: whole or large pieces of fruit, candied slowly in sugar syrup over several days until they turn translucent and glassy while still holding their shape, and then charged with mustard essence until the syrup burns the back of the nose. Cremona makes the famous version, a jewel-box of whole cherries, figs, apricots, pears, and clementines that looks like confectionery and behaves like horseradish. Mantua makes a plainer one from a single fruit, usually quince or apple, chopped rather than whole. Vicenza, Voghera, and half a dozen other towns each keep their own. The word is the same Latin mustum that gives English mustard, and the shared root is the whole explanation: both descend from the medieval habit of preserving with grape must and mustard seed together. Northern Italy kept the fruit version and largely abandoned the plain condiment, which is why Italy has almost no tradition of mustard in a pot and a very strong one of mustard in a fruit jar. Its logic is medieval and it has not changed. Sugar-preserved fruit was a luxury, mustard was a preservative and a stimulant of appetite, and the collision of the sweet and the violent was exactly to the taste of a late-medieval table that also liked its meat with sugar and cinnamon. Where it goes is fixed. Mostarda is the compulsory partner to bollito misto, the great winter platter of boiled beef, tongue, capon, and cotechino that is the centrepiece of the Lombard and Emilian table, where its sweetness and its heat cut through several hours of simmered meat. It is also served with aged cheese, and the Mantuan version is worked into the filling of tortelli di zucca.

Ingredients

Fruit

  • 400 g firm pears, peeled, cored, and quartered
  • 300 g quince or firm apple, peeled, cored, and cut into wedges
  • 200 g apricots, halved and stoned, or dried apricots
  • 150 g cherries, stoned but left whole
  • 2 whole clementines, whole, blanched three times in fresh water

Syrup

  • 700 g granulated sugar
  • 300 ml water
  • 1 whole lemon, juice only

Mustard

  • 20 drops food-grade mustard essence (essenza di senape), or to taste
  • 2 tbsp English mustard powder, as an alternative to the essence

Method

  1. Blanch the whole clementines three times, starting each time in fresh cold water and bringing to the boil, to remove their bitterness.
  2. Layer all the prepared fruit in a large bowl with the sugar, cover, and leave overnight. The sugar will draw out a great deal of juice.
  3. Next day, pour off the syrup into a pan, add the water and lemon juice, and bring to the boil. Pour it back over the fruit and leave for another 24 hours.
  4. Repeat on the third day and the fourth: drain off the syrup, boil it to reduce and concentrate it slightly, pour it back over the fruit, and leave another day.
  5. On the last day, lift the fruit out with a slotted spoon into sterilised jars. Boil the syrup down until it is thick and coats a spoon heavily, then cool it to lukewarm.
  6. Stir the mustard essence into the cooled syrup a few drops at a time, tasting cautiously between additions. If using powder instead, mix it to a paste with two tablespoons of cold water, leave ten minutes, then stir in and sieve.
  7. Pour the mustard syrup over the fruit in the jars so everything is covered, seal, and leave at least a week before eating.

Notes

Food-grade mustard essence is sold by Italian grocers and online as essenza di senape. It is extremely strong and should be handled with care and kept away from eyes; a small bottle lasts years. The mustard powder alternative gives a cloudier syrup and a rounder, less piercing heat, and is perfectly acceptable. It keeps for a year in sealed jars in a cool dark place, and the heat mellows steadily over that time. The fruit is a matter of what is good: figs, plums, melon, and whole small pears all work. What matters is that everything is firm and slightly underripe, since soft fruit will collapse over four days of syrup. Serve with bollito misto, with roast pork, with a board of aged cheeses, particularly Parmigiano and Gorgonzola, and with cold cuts. A spoonful chopped into the filling of pumpkin tortelli is the Mantuan use.
