My mom had a commercial recipe book, Fanny Farmer, I still have my copy and its my goto for the standard stuff, ie biscuits, pie crust, oatmeal cookies. But she also kept a file box of cards. at the top of the card she denoted who she got the recipe from. I still have the ones she gave me, in her careful penmanship. So I have a collection of recipes from her, my Aunt Doddy , my Gramma Dulmage and my Gramma Boyd. Alas I have no daughters so they will probably stay with me.
