I remember my grandmother (fathers mom) Aunt Fan letting us make fudge brownies in her house back in the early 60's around 1962.
Her old oven door was propped shut with an old cast iron cobblers shoe last.
My sister probably around 8 years old put too much baking powder or something in the fudge brownies and invented vulcanized rubber.
I was 4 years old at the time but remember it like it was yesterday.
I really have been cooking since before I went to school.
Sometimes it was even fit to eat.
