Lemon curd is far more popular in Europe than it is here in America. My husband's aunt first introduced me to lemon curd when we visited her in Ireland. She made a layered sponge cake with layers of lemon curd and raspberry. Simply heavenly! My mother-in-law continued to show me the ways of lemon curd on a trip to England where she topped pavlova with lemon curd, cream, and berries.
