We grew up with a mom whose career was her family. So everyday, we were served with fresh food, I get to cry while chopping the onions, experiment in the kitchen, and, the chore I hate most, do the dishes.
So naturally, mama's hands (and face, and feet, and everything of her) are all in the kitchen when she cooks. And though we (my elder sister and I) are Chemical Engineers, you can't look down on ma, she has a great wisdom of her own, as she too knows the explanations of kitchen occurrences and she does a lot of experimenting on her own. Okay, we are guilty. We teach her why the water boils (vapor pressure thinga majig) , why salt and oil is added when cooking the pasta (colligative properties) and why tenderizing meat with a fork in the boiling pot works (oooh, interesting?).
