Diane Sauce, a classic of British cuisine, is a rich and aromatic sauce typically served with steaks. It boasts a distinctive blend of flavours, featuring a base of demi-glace enhanced with Worcestershire sauce, mustard, and a hint of garlic. Often finished with a splash of brandy or cognac, the sauce is then enriched with a generous knob of butter, lending it a velvety texture and a luxurious sheen. Traditionally served in fine dining establishments, Diane Sauce elevates any dish it accompanies, bringing a touch of sophistication to the plate. Whether drizzled over a perfectly grilled fillet or served alongside sautéed mushrooms, this timeless sauce remains a favourite among those who appreciate the finer points of culinary craftsmanship.
