Crema Mexicana Agria
Crema Mexicana Agria is a Mexican style sour cream that is prepared by fermenting fresh pasteurised cream until it is thick and stiff. Its tangy flavour and rich, soft texture makes it excellent for savoury dishes, dips and garnishes. It can also be used in sauces, soups, desserts, candies and casseroles. On the Caribbean islands, the cheese is known as Crema Centroamericana.
Crema Agria can be made at home by mixing unwhipped whipping cream with sour cream in equal parts. For the cream to ferment, let it stand for at least 3-4 hours in the summers and for the whole day in the winters.
