Instructions
Cook pasta in a large pot of boiling salted water, stirring occasionally, until al dente. Drain pasta and reserve 1 cup pasta cooking liquid.
Once you have added the pasta to the boiling water, melt 1 tablespoon butter with 1 tablespoon olive oil in a large skillet over medium heat. Add shallots and stir until just soft, 3–4 minutes. Add garlic and jalapeno peppers and cook, stirring often, until fragrant, about 1 minute.
Add 1/2 tablespoon lemon juice and 3 tablespoons pasta cooking liquid to shallot mixture; add a pinch of pepper. Stir until liquid is almost evaporated, about 1 minute.
Transfer cooked pasta to skillet and add 1/2 cup reserved pasta cooking liquid. Increase heat to medium-high. Cook, tossing pasta or stirring with tongs, until liquid is almost evaporated and pasta becomes glossy, about 2 minutes. Add the remaining 1 tablespoon butter, 1 tablespoon oil, 1 tablespoon lemon juice, 1 teaspoon lemon zest, crab and half of mint.
Stir pasta until butter melts and pasta is well coated, adding more pasta cooking liquid if dry.
Divide between bowls; top with remaining 1 teaspoon lemon zest and mint. Sprinkle with Pecorino-Romano cheese and more lemon juice if desired.
