I really don't like the word "curd". This recipe was given to me by a dear friend. Her family called it Lemon Curd. I just feel better calling it lemon Butter. Lemon Butter is great on bagles, bran and blueberry muffins, cakes, cake filling, cheesecake, cookies, english muffins, french toast, ice cream, pancakes, oatmeal, parfaits, scones, tarts, toast and waffles. Freezes well too!
