LOL -- I just went to get my cookbook for the Rhubarb custard pie, and now read that others put the same recipe in! It's my favorite, too...in fact, I just made one the other day.
HINT: Rhubarbs come in different varieties. The big thick heavy red stalks make the sweetest. Peel off any fibrous red that's too thick and yucky. The green stalked variety makes a more tart pie.
