How do you keep linguini al dente?
Cook linguini 1-2 minutes under the package time, taste-test frequently, and finish cooking in the sauce. Reserve pasta water to adjust sauce consistency.
Can you make this pasta ahead of time?
Prepare the sauce up to 24 hours ahead and refrigerate. Toss with freshly cooked linguini and a splash of pasta water just before serving.
What can you substitute for heavy cream?
Use half-and-half (thinner sauce), crème fraîche, or a blend of whole milk and butter (about 3:1 ratio with added butter for richness).
How much red pepper flakes should you use?
Start with 1/4 teaspoon per pound of pasta and adjust to taste. Red pepper flakes intensify as the sauce simmers, so add gradually.
Can this recipe be scaled up for a crowd?
Yes. Double or triple all ingredients proportionally. Increase sauce simmering time by 2-3 minutes to develop flavor in larger batches.
