The processing method of geoduck is as follows:

Put the geoduck shell with its opening facing up on the chopping board, press it firmly with your left hand, and hold a sharp knife in your right hand. The edge of the shell is inserted into the bottom of the siphon between the shell and body. Next, move the knife close to the clam shell, cut the clam shell and the clam body, completely cut off the adductor tendons connecting the upper and lower shells, open the clam shell, and fully expose the clam body. At this point you will see an oval geoduck belly, also called geoduck gall, cut it off.

Put the body of the clam with its belly removed in a large bowl, and slowly pour hot water of about 80 degrees over the body of the clam. When the hot water submerges the body of the clam, you can fish out the geoduck. At this point, the tough skin of the geoduck siphon should be blistered and soft. After the geoduck is blanched in hot water, the outer skin of the siphon can be easily peeled off. After peeling off this skin, the siphon and the clam are separated.

Immerse the cut siphon in ice water, use a brush to remove the brown debris on the surface, then cut the siphon in half along the middle from where the two pores are exposed at the thick end of the siphon. And cut off the spongy object from the clam body and throw it away. Next, tilt the knife down to slice the siphon into thin slices, thus completing the treatment of the siphon.

The living habits of geoducks

Geoducks feed on single-cell algae in seawater, and can also filter feed sediments and organic debris. Its main enemies are fish such as crabs, starfish, snails and plaice. Adult shells live on the seabed and have strong protective capabilities.

Geoducks grow rapidly in the first 4 years. The 1-year-old shells are 5-6 cm long and weigh 36-40 grams; the 2-year-old shells are 8-10 cm long and weigh 200-250 grams; the 3-year-old shells The shell is 10-12 cm long and weighs 400-500 g; the fourth-instar shell is 12-15 cm long and weighs 500-800 g. As the shell grows older, the growth of the shell gradually slows down, but the growth of the soft body can still continue, and the life span can reach more than 100 years.
