Hell, I read these AMish cook articles in the Farm News and today I took a short course on how to make the "PERFECT CRAB CAKE" and I learned about the garlic trick when they were teaching us how to make the tartar sauce with a little zip.
I learned one from my dad years ago . If you are going to separate egg whites and yolks from fresh eggs, break the eggs into a funnel.(of course dont drop the egg schmutz from three feet high). When the egg empties into the funnel, the whites will spill out and the yolk will remain in the funnel..Also, dont break the egg on the edge of a pan or the dfunnel. break it on a hard counter surface, it cracks cleaner and you can break it cleanly with one hand (This is especially handy for me).
Come to think of it, I have a few one handed tricks that Ive picked up over the years
