Anything that involves takeout Chinese food is a Parent Hack in my book (or blog, as the case may be). Thanks, Mary.
I don't know if this counts as a "parent" hack, per se, but I'm a parent, and I eat a lot of carryout Chinese, so here's my hack. Normally when I try to reheat leftover rice from Chinese carryout, it comes out as dry as it went in. Not very appetizing. Instead, put the rice in a bowl or dish, put a little water at the bottom, cover with Press'n Seal or cling film, and put in the microwave for about 2 minutes. The rice will come out soft and fluffy.
Another way to revive leftover rice: add it to the top of a pot of freshly-cooked rice. The steam from the cooked rice will soften the leftover stuff. Or, add it to chicken stock (Chicken and Rice Soup), fry it up with a scrambled egg and a little chopped scallion (Fried Rice), or mix with heated black beans, some shredded cheese and a little salsa and roll into a tortilla (Burritos).
