Kitchen Guide
- → Can I use fresh shrimp instead of frozen?
Yes, fresh shrimp will work well and may reduce cooking time slightly. Adjust accordingly to avoid overcooking.
- → Is it necessary to break the pasta before cooking?
Breaking the pasta helps it fit and cook evenly under pressure inside the pot, ensuring consistent texture.
- → Can I substitute heavy cream with a lighter option?
Half-and-half can be used for a lighter sauce, but may result in a less creamy texture. Adjust seasoning as needed.
- → What can I add for extra vegetables?
Frozen peas are included, but fresh spinach or sautéed mushrooms also complement the dish nicely.
- → How should I adjust seasoning to taste?
After cooking, taste and add salt, pepper, or lemon juice to brighten flavors according to preference.
