Notes
Erren’s Top Tips
Steep the Saffron Like Tea Don’t rush the saffron soak. Steeping it in hot (not boiling) water for 8–10 minutes helps unlock both its signature golden color and that warm, slightly floral flavor. Think of it like making tea—you’re coaxing out the good stuff.Don’t Skip the Pasta Water That cloudy, salty water you usually toss? It’s liquid gold. Stirring it into the sauce helps loosen things up and gives the cream something to cling to. Add it slowly until the sauce is smooth and glossy.Zest Before You Juice It’s way easier to zest your lemon before cutting it open. A microplane gives the best fine texture, and it distributes more evenly through the sauce.Undercook Your Pasta (On Purpose) Cook your pasta just a minute shy of al dente. It’ll finish cooking in the sauce and soak up more flavor that way.Use Real Parmesan Freshly grated Parmigiano-Reggiano melts smoother and tastes so much better than the pre-shredded kind. The saltiness adds balance to the rich sauce.
Storage & Freezing Instructions
Storing Leftovers: Let the pasta cool completely before transferring it to an airtight container. Store it in the fridge for up to 3 days. When reheating, add a splash of cream or milk to loosen up the sauce—otherwise, it can get a little thick and sticky.Freezing Tips: While the cream-based sauce can be frozen, it may separate slightly when thawed. If you’re planning ahead, cook the sauce and pasta separately, freeze them individually, and combine fresh when reheating. Let the sauce thaw overnight in the fridge, then gently warm it on the stove with a bit of cream to bring it back together.Reheating Tip: Low and slow wins. Warm it gently in a skillet over low heat with a splash of pasta water, milk, or cream, stirring until smooth. The microwave works too, but stir every 30 seconds and add liquid to keep things creamy.
