I recently discovered my mother-in-law's recipe file and decided to try a few recipes from it. She already made me a lovely hand written and illustrated family cook book of her favorite recipes (I've shared a few recipes from this here), so I don't know how much she used the recipes in the file.
The first one I thought I'd try is this "banana bread cake". My husband thinks that Roslyn was a neighbor of theirs. The ingredients are similar to a cake batter, but baked in a loaf pan.
One of the issues with trying to recreate recipes from old recipe files is the recipes were always copied carefully. This goes for my mother's and my mother-in-law's hand written recipes. So, I sometimes I have to guess what they meant. For this recipe, I had to guess the amount of baking powder and size of loaf pan. There is "tsp", then ditto marks for the 2 measurements above the baking powder, and "4 tablespoons" for the sour cream measure after it. The baking powder just has a "1 t" next to it. Another banana bread recipe in the file that is similar has 2 teaspoons of baking powder, so a tablespoon seems a reasonable guess. I used the 1.5 quart Pyrex loaf pan I inherited from my mother that is, according to my husband, the same type loaf pan my mother-in-law had.
