1. Shell fava beans (you will have about 2 cups). Boil beans in salted water 2 minutes, then rinse with cold water until cool.
2. Peel tough skin from each bean by tearing it open at its round end and popping out the bean.
3. Spread crackers with a thin layer of ricotta and top with favas and mint. Sprinkle with salt and drizzle with oil.
Make ahead: Peeled fava beans, up to 1 day, covered and chilled.
Note: Nutritional analysis is per cracker (if using homemade).
