Rose is a relatively good cook, because her mom wasn’t always up for it, and she wanted some variety from easy to cook boxed meals. She generally made enough for herself, her mother, and leftovers for easy reheating. She also can make drinks like a champ, but as she got older and more bitter about her mom’s drinking, she’d just throw some juice in with a tiny bit of vodka, with the hopes it would slow her down a bit.
John doesn’t know how to cook, or do the laundry, or any of the self-sufficient things he really should, because his dad usually did them. He was forced into enough baking bonding time to be great at that, despite his wishes not to be.
Dave can’t cook that well, since it was best to be in and out of the kitchen, lest he get interrupted. Since his kitchen was generally useless anyway, and his brother made a good amount of money, he’d grab takeout, pizza, and whatever other cheap, cooked meals he could walk to most of the time for dinner, and have non-cooked food like cereal and sandwiches for breakfast and lunch.
Jade is capable of making food, but is rather blown away when she starts regularly eating well-cooked meals for the first time; she’s not used to so much flavor, from spices, or such a large variety of things to eat.
