Can I use only shrimp or only scallops?
Absolutely. Use 1 to 1 1/4 pounds total seafood. If doing all shrimp, go for large shrimp (16/20 or 21/25 count). If doing all scallops, buy sea scallops and make sure they are very dry before searing.
What pasta shape works best?
Long pasta like linguine or spaghetti is classic, but shapes like penne or rigatoni hold the sauce well too. Use what you have. The real key is saving that pasta water.
How do I keep scallops from steaming?
Dry them thoroughly with paper towels, do not crowd the pan, and make sure the pan and oil are truly hot (hot, but not smoking) before the scallops go in. Also, do not fuss with them. If they stick at first, give it a moment. When they are ready, they will release and flip cleanly.
Do I need to rinse scallops?
If your scallops have grit, you can give them a quick rinse or wipe them off with a damp paper towel, then dry them very well. Most importantly, remove the side muscle (the small, firm flap on the side). It pulls off easily and can be a bit chewy.
Can I make it without cream?
Yes. For a lighter sauce, swap the heavy cream for 1/2 cup half-and-half. Keep the heat gentle and expect a thinner sauce. Or go more olive-oil-forward: add an extra 2 tablespoons olive oil and use more pasta water to create a light lemon-garlic sauce. It will be less rich but still tasty.
Is Parmesan okay with seafood?
This is one of those “rules” that gets over-policed. A little Parmesan adds savory depth. If you prefer to skip it, use more salt and a bit of extra lemon zest, or finish with toasted breadcrumbs for texture instead.
