I test the PH of my 3 egg whites, good for me for planning ahead, right? 1st egg, PH below an 9. 2nd egg, I dropped the yolk in and the 3rd egg was at a 9 so I decided to use a pinch of BS to raise it. Which lowered more and more w/ every pinch. Darn it all! Trying to warm another in my hand asap! :)
