Paola Velez's tamarind pate de fruit is sweet, tangy, coated with fruity sugar, and all-together delicious. Because the sugar coating dissolves within an hour, cut and coat only when ready to serve. Cover and refrigerate the remaining jelly, store the fruit sugars air-tight at room temperature, and you've got a sweet treat ready to serve in minutes. Frozen tamarind pulp can be found at local Mexican grocers and some supermarkets. Look for liquid pectin in the baking aisle along with canning supplies.
