We were enchanted by Segovia-Welshs idea of cold ice cream flavored with "warming" spices such as those found in the fragrant Chinese blend called five-spice powder. It turns the honest little caramel pecan cakes into something suave.
Cooks notes:
•If you cant find dried tangerine peel, prepare your own by completely drying pieces of peel on a rack at dry room temperature, 4 to 5 days.
•Custard can be chilled up to 1 day.
•Ice cream can be made 1 week ahead.
