Recipe FAQs

Can I use fresh shrimp instead of frozen?

Yes, fresh shrimp can be used and will cook more quickly. Adjust the pressure cooking time accordingly to avoid overcooking.

Is it necessary to break the pasta before cooking?

Breaking the pasta helps fit it into the pot more evenly, ensuring even cooking and better distribution of the sauce.

Can I substitute the heavy cream with a lighter alternative?

Half-and-half can be used for a lighter, less rich sauce, though it may slightly affect the creaminess and thickness.

What is the purpose of quick-releasing the pressure?

Quick-releasing stops the cooking instantly to prevent the shrimp from becoming tough and helps retain a fresh texture.

Are frozen peas necessary?

Frozen peas are optional but add a burst of sweetness and color, enhancing the overall dish.
