Rose Foerch's Chocolate Cake

I saw the earlier post on a recipe and thought I'd add this one from my recipe book. I wrote this in my book in about 1988 just like this which I copied verbatim from the recipe, and I don’t know if I got it from Barbara Palmer or my father Ed Foerch (Barbara's brother), but my dad says this was always his favorite cake. I might have a few more kicking around - if I do, I'll post them.

Grandma’s Chocolate Cake

Pinch of salt
