Crispy rice at the bottom of the pot is a sought-after delicacy, found in dishes like paella and Persian pilaf. Making crispy rice at home is easier than you might think. Start with cooked short-grained rice, seasoned with rice wine vinegar and sugar or cooked in white wine. Flatten the rice in a pan and refrigerate overnight. Cut into squares and pan-fry until brown and crisp. Top the rice squares with tuna, either raw or canned, for a delicious and customizable bite.
