Mashed parsnips can make a lovely vegetable accompaniment but do need rich additions to improve both the texture and flavor. Dry the cooked pieces carefully before mashing, then add plenty of butter or cream, black pepper and sweet spices such as nutmeg. Some dry mashed potato can also be mixed into mashed parsnip to lighten it and this makes a good topping for shepherd's or cottage pie. Carrots and parsnips mashed together make a tasty and colorful dish to go with plain grilled meats.
