I just remembered a thing I tasted about 60 years ago. I was renting a basement apartment from a friend & his wife. One day she came down and knocked on my door...said she wanted me to taste something she had baked.
She gave me a slice/chunk of something that looked vaguely like cake, but not very thick.
   It tasted 'different'. Kinda nutty, kinda like dark bread or an odd cake, but chewy... hard to describe, but very nice!

"Well", she said, "I wanted to bake a cake, but didn't have the right stuff and no time to go to the store, so I took a box of "Jiffy Cornbread Mix" and a box of I.G.A Buttermilk pancake mix, and combined them with a little sugar and some milk."

I told her she had a great invention there... however, she kept the rest for herself, her husband and their son, and I never got another bite. I've been meaning to try that ever since! Maybe soon....
