To prepare a sweet and tangy tamarind date sauce recipe, first you will need to gather your ingredients. First, you'll need the following ingredients: 12 cup (120 ml) fresh or frozen ripe dates, 2 tablespoons (15 g) sugar, and 1 teaspoon (2.5 grams) ground cinnamon. You can also use dried dates if you don't have fresh dates. Cut the dates in half and remove the pits. Peel the rinds and cut them into 1/4-inch (.6 cm) thick slices. Place the slices in the food processor and pulse them until they're finely chopped. Add the sugar and puree until the mixture is smooth and creamy. Pour the sauce into jars or sealable containers and refrigerate until ready to use.
