The test kitchen prefers a crisp made with Bartlett pears, but Bosc pears can also be used. The pears should be ripe but firm, which means the flesh at the base of the stem should give slightly when gently pressed with a finger. Bartlett pears will turn from green to greenish-yellow when ripe. Although almost any unsalted nut may be used in the topping, we prefer almonds or pecans. Serve the crisp with lightly sweetened whipped cream or vanilla ice cream.
