We still use Mom’s Household Searchlight Recipe Book from 1938. Still has her handwritten addition of a lefse recipe.
She used to joke that our underwear said Gold Medal Flour.
I don't know that one. One I inherited from my grandmother was the Settlement Cookbook. That goes back to about 1900, so you know it's a no-nonsense guide. It was reissued not so terribly long ago. I found one in a store and anxiously opened it to chicken soup -- and was immensely relieved to see that the recipe still includes chicken feet :-)
So what IS your mother's lefse recipe? Don't just brag about having it, share!
