Piquante is demi-glace sharpened with a white wine and vinegar reduction, garnished with cornichons, capers, tarragon, chervil, and parsley. It is the sauce for leftover meats — specifically, rôti de porc réchauffé (reheated roast pork) — and its genius lies in using aggressive acidity and pungent garnishes to compensate for the flavour loss that occurs when meat is cooked, cooled, and reheated. In a tradition that wasted nothing, Piquante ensured that yesterday's roast tasted as compelling as today's. Sweat 2 tablespoons of finely minced shallots in butter until translucent. Add 100ml of dry white wine and 50ml of white wine vinegar. Reduce by two-thirds — the reduction should be intensely sharp, almost uncomfortable to taste alone. Add 400ml of demi-glace and simmer for 15 minutes. Strain through a fine chinois. Prepare the garnish: 30g of cornichons (the tiny French gherkins, not American dill pickles), cut into 3mm rounds; 1 tablespoon of small capers, drained and rinsed; and 1 tablespoon each of chopped tarragon, chervil, and flat-leaf parsley. Add the cornichons and capers to the hot sauce. Add the herbs off heat — they discolour within seconds in hot liquid. The finished Piquante should taste sharp first (the vinegar reduction), savoury second (the demi-glace), and finish with bursts of brine (capers, cornichons) and fresh herb. It should provoke appetite, not satisfy it — the sauce's role is to make you want to eat more of the meat it accompanies. Piquante and Sauce Charcutière share parentage — Charcutière is essentially Sauce Robert (mustard-onion espagnole) with the same cornichon garnish. The two sauces sit side by side in every classical reference because they solve the same problem (sharpening pork) from different angles: Piquante through vinegar and herbs, Charcutière through mustard and onion.
1. The vinegar-wine reduction must be aggressive — reduced by two-thirds minimum. 2. Cornichons, not dill pickles — the smaller size and sharper flavour are essential. 3. Herbs go in off heat. 4. The sauce must provoke appetite — if it is balanced and polite, it has failed. 5. This is a sauce for reheated or leftover meat — its sharpness compensates for flavour loss.
Add a teaspoon of Dijon mustard alongside the vinegar reduction — it bridges the gap between Piquante and Charcutière and amplifies the sharpness. For roast pork service, warm leftover pork slices gently in the sauce itself for 5 minutes — the meat absorbs the flavour and the sauce body thickens slightly around the meat. This is the traditional method and superior to napping cold pork with hot sauce.
Not reducing the vinegar base enough, leaving the sauce generically tart. Using American pickles instead of French cornichons — completely different flavour profile. Adding herbs to hot sauce and cooking them into grey mush. Making the sauce too thick — Piquante should be pourable, not a paste.
