Hey Kim, Thank you! The trick to getting sauce and pasta to stick together, the Italian way, is to add a small amount of reserved pasta cooking water with the sauce and noodles. The starchy water allows the sauce to perfectly stick to the noodles. So I would reserve a small amount of pasta water, toss the rest down the drain, and add that small amount of water to the sauce/noodles when you combine the two in the Instant Pot before serving.

I re-read that portion in the recipe card and realize that was very confusing, too. Sorry about that. Hopefully this clarifies 🙂
