My daughter is having a birthday party on Sunday and I plan to use my grandfather's frosting recipe. He used to be a baker and I remember him making cakes and frosting from scratch for family members. His recipe is pretty simple: about 1/2 lb shortening to 1 lb confectioner's sugar with a hint of vanilla. He did mention sometimes you need to add a little of this or that to get it just right, and it just takes practice to get the feel for it. His frosting has never been "oily" like I've heard a lot of people say about this type of frosting, and I want to get it just right like his. My problem is this: my dad bought the ingredients for me and the shortening he got is cut with lard. Lard is listed as the first ingredient. I am afraid that this might affect the taste and consistency in some way and am wondering if I should get 100% vegetable based shortening. My grandpa swears by Crisco. What are your opinions or advice for me?
