When I was a kid, I had a Betty Crocker cookbook for kids; and it had a sugar cookie recipe.
I made them, without realizing that my grandmother’s self-rising flour already had salt; so I added the salt called for in the recipe.
To this day, I like my sugar cookies very salty! They weren’t ruined, they were interesting :-)
In my young bachelor days, I decided to bake a chocolate cake. And I wanted twice the frosting, so I doubled the frosting ingredients. Strangely, using twice as much baker’s chocolate gave an icing similar to coating the cake in Hershey bars. I still don’t under stand why two times two equals five.
You live......you learn.
