How to Make It
Quarter shrimp by halving lengthwise and then crosswise. Place in a colander, and sprinkle with salt. Massage shrimp with salt; let stand in sink 5 minutes. Rinse shrimp; shake colander to remove excess water. (You’ll want a little residual water).
Transfer shrimp to a bowl; toss with ginger, garlic, and jalapeño. Heat oil in a medium skillet over medium high until it shimmers. Add shrimp mixture; cook, stirring occasionally, until just cooked through, about 3 minutes. Add wine and cook, stirring occasionally, until half of wine has evaporated, about 2 minutes. Stir in parsley and butter; cook until butter melts. Spoon over toast.
