Your move
Decision guide
Choose Cuttlefish
- You are on a strict cutting phase and need maximum protein with minimal calories.
- You are unconcerned about dietary cholesterol.
- You want a firm, meaty texture for seafood dishes.
Choose Mussels

Practical
Consumer tips
- 1
Cook Cuttlefish either very quickly (2 minutes) or very slowly (45+ minutes) to avoid a rubbery texture.
- 2
Never eat Mussels that do not open during cooking; this is a clear sign they were dead and potentially toxic.
- 3
Limit Cuttlefish portions if you have high blood cholesterol, as a single serving packs a massive amount.
- 4
Soak Mussels in cold water for 20 minutes before cooking to help them purge sand.
