If I buy groceries and provide a recipe, the teens can make dinner. In this case, the mushroom bisque from Cook's Illustrated, and roasted parsnips, carrots, and Brussels sprouts. (The beige thing next to the soup is store-bought garlic bread. It was, by far, the least delicious thing on the plate.)
Granted, by the time I was their age, I could (and did) make meals for the family.
But now there is Google. The boys can research recipes and come up with their own ideas. And they also have a grocery store within a mile--many more possibilities than back in my day.
They still have lots of questions and need a certain amount of guidance. And granted, the texture of the bisque wasn't QUITE as smooth as I'd make it, and the Brussels got a bit crispier than I'd like. And yet, I didn't have to do any of it.
Not even dishes.
And later, one of them brought me a dish of ice cream.
