This Crab Marinara is made with blue crabs, San Marzano peeled tomatoes, red pepper flakes, garlic, basil and served on pasta.

This is a delicious crab sauce on spaghetti that you can make for a nice warm summer day. Your local fish market will clean the crabs for you.
Blend the whole plum tomatoes into a puree with a blender or a food processor. Alternatively, you can squish them with your hands if you like your sauce on the chunkier side.

Substitutions

- Red pepper flakes: Red pepper flakes make the dish spicy.
Variations
Cooking is a chance to be creative! Have fun with it and feel free to make your own variation.
- Spicy - add extra chili pepper flakes while cooking to imbue heat into the dish.

- Kid friendly - use fun sized pasta for this dish.

Equipment
Equipment can have a big impact on how a recipe turns out. Stone bakeware takes longer to heat up than metal pans, and also retain heat for longer, which could make the recipe more watery, or burnt on the outsides.

Storage
This will be good in the refrigerator for 2-3 days.
These ingredients don't stand up well to freezing.
Top tip
Make sure the crabs are nestle int he sauce completely before covering.
