My little boys love to help me in the kitchen. So when a task made for little hands, like scrubbing potatoes, comes along, I put them right to work -- they have fun, the potatoes get scrubbed, and I can turn my attention to something else, perhaps the chili on the stove (chili over baked potatoes! Yum!), for a minute or two.
Mmmm. Cleanest potatoes in town!
(Good news: The soap rinsed well and left no discernable residue. And the boys enjoyed rinsing them almost as much as scrubbing!)
