Potatoes and parsnips mashed together with a little garlic, sour cream and butter make a surprisingly tasty side dish. The parsnips add a slightly sweet and spicy taste to the potatoes that I really enjoyed.

Reduce heat and simmer vegetables, partially covered, until very tender but not falling apart, 30 to 40 minutes.
