Pasta with Rock Shrimp, Chile, and Lemon
Ingredients
Method
Melt butter in a small saucepan over medium-low heat, then add bonito flakes; swirl butter to combine. Remove from heat and let sit 10 minutes to infuse.
Strain butter through a fine-mesh sieve into a small bowl, pressing on solids; discard bonito flakes. Cover and chill butter until ready to use.
Finely grind dried shrimp in spice mill or with mortar and pestle; set aside for serving.
Cook pasta in a large pot of boiling salted water, stirring occasionally, until very al dente, about 3 minutes if using fresh pasta, longer if dried. Drain pasta, reserving 1 1/2 cups pasta cooking liquid.
Meanwhile, heat oil in a large skillet over medium. Add chile and lemon zest and cook, stirring, 20 seconds. Add rock shrimp and cook, tossing, 1 minute. Add tarragon, lemon juice, pasta, 3/4 cup pasta cooking liquid, and 3 Tbsp. bonito butter and toss to coat. Cook, tossing and adding more pasta cooking liquid as needed, until sauce is glossy and coats pasta and shrimp are cooked through, about 3 minutes. Season with salt if needed.
Divide pasta among bowls and top with scallions and reserved dried shrimp.
