In my family, if you wander near the kitchen at mealtimes, you're bound to be put to work. When my brother and I were younger, we did simple things like grating cheese or shredding lettuce with our hands. When we got older, we were giving a paring knife and a pile of fruit to make into fruit salad. My mother eventually gave me a spatula and put me on stir-fry duty.
One of the first "recipes" I learned to make was a simple balsamic vinaigrette for the salad. I remember taking my responsibility very seriously, carefully measuring out spoonfuls of olive oil and vinegar before gleefully whisking them together. I didn't actually like the vinaigrette, mind you, but I felt very proud of making it.
How do your kids help with cooking?
