I tend to buy frozen seafood for convenience sake. It is wise to soak and shellfish prior to cooking though to get rid of any sand or grit that might be lurking.

The quantities in this recipe are just a rough guide. Add more prawns, or less squid if there’s something  you prefer or don’t like.

I love clams but you can also use mussels. It can be bulked out with more pasta and tomatoes if you’re feeding a whole family. I’ve found it makes a small amount of seafood go a long way, which is always good!

If you haven’t tried one yet, multicookers are great for cooking your pasta. They’re also ideal for steaming, which is perfect for cooking that all important speed veg. You can pick one up on Amazon.
