Hashed Brussels Sprouts With Lemon Zest

Hashed Brussels Sprouts With Lemon Zest
Adapted from “The Union Square Cafe Cookbook” by Michael Romano and Danny Meyer
This is a pain-free way to cook a whole lot of brussels sprouts, so long as you have a food processor.

INGREDIENTS
2 tablespoons freshly squeezed lemon juice, more to taste
Grated zest of 1 lemon
1kg brussels sprouts
2 tablespoons olive oil
2 tablespoons butter
3 garlic cloves, minced
2 tablespoons black mustard seeds, cumin seeds, or poppy seeds
1/4 cup dry white wine
Salt and pepper to taste

PREPARATION
Place lemon juice in a large bowl. Cut bottoms off sprouts, and discard. Working in batches, use a food processor fitted with the slicing blade to cut sprouts into thin slices. (If cutting by hand, halve sprouts lengthwise, and thinly slice them crosswise. The slices toward the stem end should be thinner, to help pieces cook evenly.) As you work, transfer slices into bowl with lemon juice. When all sprouts are sliced, toss them in juice and use your fingers to separate leaves. (Recipe can be prepared to this point and refrigerated, covered, for up to 3 hours.)
When ready to serve, heat oil and butter over high heat in a skillet large enough to hold all sprouts. When very hot, add sprouts, garlic and seeds, and cook, stirring often, until sprouts are wilted and lightly cooked, but still bright green and crisp, about 4 minutes. Some leaves may brown slightly.
Add wine and sprinkle with salt and pepper. Cook, stirring, 1 minute more. Turn off heat, add salt and pepper to taste, and more lemon juice if desired. Stir in the lemon zest, reserving a little for top of dish. Transfer to a serving bowl, sprinkle with remaining zest and serve.
