I wanted to make my daughter a slammin pizza today by using gleefully ripe Plum tomatoes from our own garden. After close inspection of all food, spices and other worldly cooking stuffs worthy of pizzadom, I realized to my dismay I didn’t have yeast for “Operation Make-a-da- Pizza”. I thought; “Do you really want to go out to the megamart for yeast?” I decided to see if I’ve got the grapes for the job. and headed outside to pick a bowls worth of grapes growing on our property. I had hopes of making enough yeast with the grapes to make a killer pizza. First thing done with the grapes was to make sure they weren’t any nasty bits or fruit sporting any kind of hidden bug co-ops, lurking in with the other grapes . Grapes were then put into a stainless steel bowl with about three cups of 107 degree filtered water. A pinch of sugar was added as an insurance and snack for the beautiful little beasties to partake of . After that he whole lot was gracefully placed atop of my modified/pimped cup warmer that I enjoy using for keeping my tea nice and warm as I do super duper important stuff around the house. I put enough Insulation around the heating plate to allow just enough surface area to touch the bowl and keep it warm but not too warm. You want it to be warm enough to let the yeast love fest to Begin the Beguine, but not too much. If the water is too hot the yeast will stop growing and could very well take that big trip the leavening here-after. Depending on where you get you information it’s generally believed that over a 120 degrees will cause your yeast to play dead for real.
I think body temperature to about 110 degrees fahrenheit is a good place to be on the yeast love boat.
I’ll let you know how it goes.
