Put very ripe tomatoes, cut in half but with seeds and all, into a stoneware or earthenware jar. Leave to ferment for eight days, taking care to stir daily with a wooden spatula. When the eight days are up, strain the contents into a bowl. Crush the tomatoes carefully with a masher, and pour the sauce obtained into a cloth bag to remove all the liquid. Hang the bag and let it drain for two days.

Spread the coulis on a plate and leave it out in the sun to dry for several days. Add salt to taste and stir with a wooden spatula. Fill small jars with the coulis and cover with olive oil. Close the jars with waxed paper (or lids).
