1Place lemon juice in a large bowl. Cut bottoms off sprouts, and discard. Halve sprouts lengthwise. If you are really ambitions, carefully cut out and discard the firm core of each sprout half. Thinly slice the sprouts. As you work, transfer slices into bowl with lemon juice. When all sprouts are sliced toss them in juice and separate leaves. (Recipe can be prepared to this point and refrigerated, covered, for up to 3 hours.)
2When ready to serve, heat oil and butter over high heat in a skillet large enough to hold all sprouts. When very hot (almost to smoking point) add sprouts, garlic and pepper, and cook, stirring often, until sprouts are wilted and lightly cooked, but still green and crisp, 3 to 4 minutes. Some leaves might brown slightly.
3Add wine, and sprinkle with salt. Cook, stirring, 1 minute more. Turn off heat, add salt and pepper to taste and stir in the lemon zest, reserving a little for top of dish. Transfer to a serving bowl, sprinkle with remaining zest and serve
