Potato Parsnip Mash

Step 1

Cover parsnip and potato with cold water by 1 inch in a 3-quart saucepan, then add salt and bring to a boil, partially covered. Reduce heat and simmer vegetables, partially covered, until very tender, 10 to 15 minutes.

Step 2

Reserve 1/4 cup cooking water, then drain vegetables in a colander. Return vegetables to pan and coarsely mash with a potato masher or a fork, discarding any tough core from parsnip if necessary. Stir in butter, 2 tablespoons reserved cooking water, and salt and pepper to taste. Thin with additional cooking water if desired.
