Garlicky Mashed Parsnips

I made this last night with some local parsnips.  The ones I had turned out to have a disappointingly bitter note to their flavor, but the rest of it came together nicely.  I'll be trying it again in the spring.

1 lb parnips, peeled and cut into 1/2-inch rounds

1 head roasted garlic, cloves peeled

1/4 cup milk plus more to taste

2 Tbsp butter plus more if desired

Salt and pepper to taste

Steam or boil the parsnips until tender.  Mash in a bowl with the garlic, milk, and butter until they reach the desired consistency.  Add salt and pepper.  Serve hot.

Serves 4-6.
