Mint sauce

The English condiment that has accompanied roast lamb for centuries: bruised fresh spearmint leaves macerated in malt vinegar and sugar, sharp and herbaceous

Origin: England

From the journey of Mint.

Mint sauce is England's great herb condiment; simple to the point of austerity, yet irreplaceable in context. The preparation has remained essentially unchanged for centuries: fresh spearmint leaves are bruised, macerated in a small amount of sugar (which draws out the juices), then covered in malt vinegar and left to steep. The result is a thin, dark green sauce; not a chutney, not a purée; with a sharp, bracingly vinegar-forward character that cuts through the fat of roast lamb with surgical precision. English cookbooks from the 17th century onwards describe mint sauce in essentially identical terms; the method has not evolved because it does not need to. The combination of mint and lamb reflects a genuinely ancient association; both the Romans (who spread the cultivation of both sheep and spearmint across Britain) and earlier medieval English cooks paired the two; and the particular English expression of that pairing, through vinegar rather than through yogurt or lemon as in the Greek, Persian, and Indian traditions, reflects the English access to malt vinegar as a pantry staple. Mint sauce is one of those national food objects that provokes strong reactions from visitors: the French consider it barbaric applied to good lamb; the English find any other application of mint to roast lamb incomplete. Both positions are correct within their own culinary logic.

Ingredients

mint

  • 1 large bunch fresh spearmint, approximately 30g leaves, stems removed

sweetener

  • 1 tsp caster (superfine) sugar

vinegar

  • 3 tbsp malt vinegar, the specifically English malt vinegar is traditional; white wine vinegar is an acceptable substitute

liquid

  • 1 tbsp boiling water

seasoning

  • 1 pinch fine sea salt

Method

  1. Wash and thoroughly dry the mint leaves. Pile them on a chopping board and sprinkle the sugar over them. Chop the mint and sugar together finely: the sugar acts as an abrasive, bruising the mint as it's chopped and drawing out the juice. Continue until you have a fine, damp herb mixture.
  2. Transfer the chopped mint to a small bowl or jug. Add the boiling water and stir: this briefly brightens the mint's colour and softens its raw edge. Allow to cool for 2 minutes.
  3. Add the malt vinegar and a pinch of salt. Stir well. Taste; the sauce should be sharp, herby, and slightly sweet. Adjust vinegar and sugar to your preference.
  4. Allow to stand for at least 10 minutes before serving: the mint continues to steep in the vinegar and the flavour deepens. Serve at room temperature alongside roast or grilled lamb.

Notes

Spearmint (Mentha spicata) is the traditional choice; its sweetly aromatic character suits the vinegar base. Peppermint would make the sauce taste like a medicine cabinet. The sauce should be thin and pourable, not thick; this is not a chutney. Many commercial mint sauces use distilled malt vinegar and mint extract; the homemade version with fresh leaves is dramatically different. Serve alongside the traditional English roast lamb, or with lamb chops.
