Can I make this without vodka?
Yes. Omit the vodka or replace it with 1 oz dry white wine. The vodka adds a subtle kick and helps emulsify the sauce; its alcohol burns off during cooking.
How do I know when the lobster meat is cooked through?
Fresh lobster meat is typically already cooked. If using raw lobster, cook it separately until opaque and firm (about 8–10 minutes), then chop and add to the sauce at the end.
What pasta shape can I use instead of lumache?
Lumache's ridged, shell-like shape traps sauce well. Substitute with rigatoni, penne rigate, or conchiglioni for similar texture and sauce cling.
How spicy is this dish?
The heat comes from 1 tbsp Calabrian chilis—this delivers moderate heat. Reduce to ½ tbsp for mild, or increase to 1½ tbsp for very spicy.
Can I prepare the sauce ahead of time?
Yes. Make the sauce (through the cream step) up to 2 days ahead; store covered in the refrigerator. Reheat gently over low heat and add fresh basil and lobster just before serving.
