Pineapple quince
With a flavor that resembles its tropical namesake, the pineapple quince from California is the most common variety available in the United States. Like most varieties of quince, it is hard and tart, so it is primarily used for cooking.
Apple quince
A sweeter variety of quince, called the apple quince, was developed in the 1990s. Unlike most quinces, this variety can be enjoyed raw.
