The leftover nubs of cheese from entertaining may not be pretty, but they are still delicious. You can give them new life by turning them into a Boursin-like spread. A mixture of medium-firm cheeses works best. Don’t leave out the vermouth, as it helps meld the flavours together. This makes more than you need for a single gathering, but it will keep in the fridge if tightly covered for at least two weeks—and is also excellent on sandwiches.—Eshun Mott
