6. How to choose fresh clams

Choosing fresh clams is very important to ensure your sour soup is delicious and of high quality. Here are some simple tips to help you choose delicious clams when shopping.

• For whole clams: You should choose clams with hard shells, intact, and heavy in your hand. Fresh clams usually keep their shells tightly closed; if some are slightly open, they will snap shut when touched. Conversely, clams that are wide open without reaction, have cracked shells, or emit a strong fishy odor are likely dead and should not be bought.

• For pre-shelled clams: Prioritize choosing clam meat with a natural bright color, looking fresh, and feeling resilient when pressed. Avoid choosing clams with a foul odor, slimy texture, or dull color, as these may be old clams that are no longer fresh.
