It has a brown handle with silver studs. She can take the skin off a whole potato without stopping. It looks easy. An old sheet of newspaper is laid out on the draining board; the peelings coil around each other like dark snakes. There’s a pan of salty water ready on the worktop.

See if you can peel the lot by the time I get back from Dolly’s.
