E loves all things kitchen. In his play kitchen, he prepares elaborate meals with unusual menu items like lettuce soup. At the children's museum he loves the laminated recipe cards and shops for all the ingredients on every card.
For Christmas I bought him a recipe box with kids' recipes, and he has selected a couple that we've made together. He helps shop, prep, and garnish.
Of course, Em helps. She is often his sous in the imaginary kitchen adventures and usually looks on during our cooking sessions. She is an eager taste tester as well.
