As our loyal reader knows, we love to mash vegetables here in the F,NRS NYC office. Recently, parsnips have come under the masher, to good effect. I only post it here because we mash these babies for Liz and Lisa, who eat kosher and therefore can't have milk or butter in the mash (if it is to be eaten with chicken, as it so often is), and Liz needs the recipe. These mashed are vegan so that we can all eat meat, if you know what I mean.
Before starting, if you want them garlicky, put many peeled cloves of garlic into a dish with many tablespoons of olive oil and put it into a low oven (say 300 F) to soften and sweeten. Then cut up—no need to peel, as far as I am concerned—parsnips, potatoes, and carrots into substantial chunks for boiling. I usually go something like four parsnips for every potato and carrot, but mix it up! Boil the parsnips for 30 minutes and the carrots and potatoes for 20. That is, you want the parsnips very done. Save some of the cooking water (remember, no milk will be permitted). Mash it all with the garlic and olive oil from the oven (or just plain olive oil if you don't want to go garlicky), insane amounts of salt and some pepper, and just enough cooking water (not much) to get them mushy.
These mashed parsnips are so sweet, you can't help asking: Parsnips, where have you been all my life?
