For a thicker chowder, mash some of the cooked potatoes before adding the seafood. - What kind of seafood works best?
Use a mix of shrimp, scallops, clams, and crab meat for the best flavor and texture. - Can I make it dairy-free?
Substitute coconut milk or a plant-based cream alternative for the half-and-half. - How to avoid overcooked seafood:
Only add seafood in the last 30 minutes to prevent it from becoming rubbery.
