Cinnamon sugar apples
I happen to know that Kate (author of the divine motherhood zine Miranda) is a great cook, because she's made me lunch on more than one occasion. I now expect this for dessert the next time I see her (do you hear me, Kate?):
I don't know if this qualifies as a hack, but a few weeks ago I got the idea to sprinkle the cinnamon-sugar shaker (previously reserved strictly for toast) over a bowl of sliced apples. The boys love it. The sugar is minimal but knowing it's there transforms what they used to consider a ho-hum snack into a big treat.
