My wife is currently unable to consume any dairy as our breast-fed baby has a milk protein allergy. When reading many dessert recipes, many of them call for butter. For example:
http://smittenkitchen.com/2008/04/shaker-lemon-pie/ or http://chefmichaelsmith.com/Recipe/cinnamon-rolls/
- I know pie crusts for example can be made with either, but can they always be substituted?
- When would I not want to use lard over butter?
- What ratios should I use to convert the recipe?
- Is there some other milk-protein free alternative that would work better?
