Mollusks are a really interesting bunch of shellfish, and they include things like clams, mussels, oysters, squid, and octopus. People really value them in cooking all around the world because of their one-of-a-kind textures and flavors. But, getting mollusks ready the right way is really important for food safety, boosting flavor, and getting that perfect texture. In this guide, we’ll walk you through a simple step-by-step process for picking, cleaning, storing, and cooking mollusks to get the best results.
Understanding Mollusks
What Are Mollusks?
Mollusks are a diverse group of invertebrates that include animals such as snails, clams, and octopuses. They possess soft bodies, often protected by a hard shell. Mollusks play significant roles in various ecosystems and exhibit a wide range of forms and behaviors. The phylum Mollusca includes three primary culinary categories:
- Bivalves: Clams, mussels, oysters, scallops.
- Gastropods: Snails, whelks, abalone.
- Cephalopods: Squid, octopus, cuttlefish.
Nutritional Benefits of Mollusks
Mollusks provide a wealth of lean protein, omega-3 fatty acids, vitamins B12, A, D, and essential minerals such as iron, zinc, and selenium. They consume it to support heart health, enhance cognitive function, and improve overall well-being.
Selecting Fresh Mollusks
How to Identify Fresh Mollusks
- For bivalves (clams, mussels, oysters):
- Shells should close or be closed when tapped.
- No strong, unpleasant smell—fresh mollusks just have that nice sea scent.
- For gastropods (snails, whelks, abalone):
- Make sure the shells are whole and have no cracks.
- It should pull back into its shell when you touch it.
- For cephalopods (squid, octopus):
- Skin should feel firm and have a bit of a translucent quality to it.
- Everything looks good—no signs of excessive slime or discoloration.
Where to Buy High-Quality Mollusks
- Buy from well-known seafood markets or suppliers you can trust.
- Check for live bivalves that are kept on ice instead of being underwater.
- If you can not find fresh cephalopods, go ahead and grab some frozen ones instead.
Signs of Spoilage
- Shells that stay open even when you give them a little tap.
- There is a really strong, fishy smell.
- It is got a weird color or feels slimy.
How to Clean Mollusks the Right Way
General Cleaning Techniques
- Give those mollusks a good rinse under some cold running water.
- Get rid of any visible debris or sand.
How to Clean Clams and Mussels

Storage and Handling
Best Practices for Storing Fresh Mollusks

- Keep cleaned cephalopods in airtight containers and place them on ice.
Freezing vs. Refrigeration
- Consume bivalves fresh for the best experience, but you can freeze them if you shuck them first.
- Cephalopods freeze effectively and store for months.
Shelf Life of Mollusks
