Rougaille Saucisse
Rougaille is the workhorse tomato sauce of Mauritian Creole cooking, used as a condiment with dholl puri, as a sauce for fried fish, and (most often) as the base of a one-pot meal with sausage, salt cod or eggs. The structure is simple but specific: onion softened slowly in oil, then ginger, garlic, chilli and fresh thyme bloomed in that oil, then a long-cooked mound of ripe tomatoes broken down until the oil splits and the sauce darkens. No curry powder, no garam masala, no coconut milk; rougaille belongs to the Creole rather than the Indo-Mauritian tradition, and its identity is the herbal punch of thyme and ginger against tomato. Rougaille saucisse, the version with smoked Mauritian-style sausages, is the textbook home preparation. Use any decent smoked, coarse-cut pork sausage; in the UK, smoked chipolatas or Polish kielbasa are good stand-ins. Difficulty is low and the cook is mostly passive. Serve with rice, a few leaves of bredes (sauteed greens) and a chilli pickle on the side.
