We asked pastry chef Michael Laiskonis if we could compare two versions of the custard in his tart: one made with fresh pumpkin, the other made with canned, which he likes for its reliable consistency. When we tested the two tarts, we were surprised to find that we also preferred the custard made with canned pumpkin — but the choice is yours.
Cooks' note:
Dough and filling can be made 2 days ahead and chilled separately, covered.
