Skordalia

Ancient Greek garlic sauce: crushed garlic with bread or potato, olive oil, and lemon

Origin: Greece

From the journey of Garlic.

Skordalia (σκορδαλιά; from σκόρδο, skordo, garlic) is one of Greece's oldest preparations: a thick, pungent garlic sauce made by pounding raw garlic with either stale bread soaked in water or boiled potato, then beating in olive oil and sharpening with lemon juice or white wine vinegar. The bread version is older and more traditional, producing a smooth, paste-like sauce of considerable intensity; the potato version arrived after the introduction of the potato to Greece in the 19th century and is today the more common taverna version, lighter in texture and slightly more forgiving in flavour. The sauce is the direct descendant of the garlic preparations documented in ancient Greek sources. Hippocrates (c. 460–370 BCE) prescribed garlic extensively for respiratory and digestive conditions, listing it among the most medicinally powerful foods available. Aristophanes, in the 5th century BCE, made jokes about garlic-breathed Athenian theatre audiences; evidence that raw garlic consumption was already thoroughly embedded in Athenian daily life. Greek athletes consumed raw garlic before Olympic competition as a perceived strength and endurance enhancer. The ancient Greek word for garlic, σκόρδον (skordon), is preserved in skordalia's name, an unbroken etymological thread connecting the modern sauce to its ancient forebear across two and a half millennia. Skordalia is uncompromisingly garlicky; raw garlic, not cooked, pounded to a paste, is the non-negotiable foundation. A good skordalia should be genuinely pungent and confrontational, not polite. The quantity of garlic called for in authentic recipes would alarm a cautious cook: six cloves is a minimum; ten is not unusual in older Greek recipes. The sauce is served alongside fried fish; particularly bacalao (salt cod, battered and fried), which is the traditional Good Friday preparation across Greece, the most garlic-heavy day in the Greek culinary calendar; with roasted beets, with fried zucchini, with grilled octopus, or simply spread on bread. The contrast between fried food and the raw, punchy sauce is one of Greek cooking's most satisfying flavour structures. The technique for both versions is the same in its essential logic: garlic is first reduced to an absolute paste by pounding with salt, which acts as an abrasive; the base (soaked bread squeezed dry, or warm mashed potato) is then incorporated into the garlic paste; and olive oil is beaten in gradually, alternating with the acid (lemon juice or vinegar), exactly as one would make a mayonnaise; because the emulsification principle is identical. The result should be thick enough to hold its shape on a spoon, creamy and smooth, with no discernible fibres of garlic remaining.

Ingredients

Garlic base

  • 6 cloves garlic (up to 10 for a fully authentic, pungent version), peeled
  • 0.5 tsp coarse salt (for pounding the garlic)

Bread version base

  • 150 g stale white bread, crusts removed (for the bread version)

Potato version base

  • 400 g starchy potatoes, floury variety such as Maris Piper or russet (for the potato version)

Emulsion

  • 120 ml extra virgin olive oil, good quality

Acid

  • 2 tbsp white wine vinegar (traditional) OR juice of 1 lemon, or a combination of both

To serve

  • Extra olive oil, to drizzle when serving
  • Chopped flat-leaf parsley (optional), to finish

Method

  1. If making the bread version: tear the crustless stale bread into rough pieces and submerge in a bowl of cold water for 5 minutes until thoroughly soaked. Take up the bread by the handful and squeeze out as much water as possible; it should be damp but not wet. Set aside. If making the potato version: peel and quarter the potatoes, cover with cold salted water, bring to a boil and cook until completely tender, about 20–25 minutes. Drain and pass through a ricer or mash thoroughly while still hot. Do not use a food processor: this makes potato gluey. Set aside while still warm.
  2. Place the peeled garlic cloves in a large mortar with the coarse salt. Pound with the pestle, working in a circular grinding motion, until the garlic is reduced to a completely smooth, wet paste with no visible chunks remaining. This typically takes 3–5 minutes of sustained effort. The salt acts as an abrasive to break down the garlic cell walls completely.
  3. Add the soaked squeezed bread (or warm mashed potato) to the mortar in several additions, pounding and working it thoroughly into the garlic paste after each addition until combined. The mixture will become a cohesive, thick paste.
  4. Begin adding the olive oil in a very slow, thin stream, almost drop by drop at first, while beating the mixture vigorously with the pestle (or transferring to a bowl and beating with a wooden spoon). Alternate between the olive oil and a small splash of vinegar or lemon juice: a little oil, then a few drops of acid, then more oil. This alternation helps the emulsion form and prevents the sauce from becoming greasy and separated.
  5. Continue alternating oil and acid until all the olive oil and all the vinegar or lemon juice have been incorporated and the sauce is smooth, thick, and creamy. Taste for seasoning and adjust salt and acid as needed. The flavour should be intensely garlicky and notably sharp from the acid.
  6. Transfer to a serving bowl. Drizzle generously with additional olive oil and scatter over chopped parsley if using. Serve at room temperature alongside fried salt cod, roasted beets, fried zucchini, or simply with good bread.

Notes

The bread version of skordalia is historically older and arguably more interesting: it produces a denser, more paste-like sauce with a slight chewiness and a flavour that is purely about garlic and acid, since bread has no competing flavour of its own. The potato version is milder in overall flavour, lighter in texture, and more common in modern Greek cooking. Both are correct; both are delicious. For a Good Friday table, skordalia alongside fried salt cod (bacalao) is obligatory; the combination is one of the defining flavour memories of Greek Orthodox culinary culture.
