How to clean shells

Put the shells in a basin of water, add two spoons of salt and one spoon of cooking oil to form an oil film on the surface. As time goes by, the oxygen content in the water continues to decrease. At the same time, due to the stimulation of salt, the shells will soon spit out sand, and rinse them with clean water. You can also repeat several times until the shells spit out all the sand.

There are many types of shells, and bivalves with smooth surfaces can be removed with a simple salt and cooking oil spitting method.

Bivalves with many grooves on their shells, such as oysters and scallops, need to be scrubbed clean under running water.

For single-valve shells such as abalone, you need to remove the internal organs of the teardrop-shaped shadow and then scrub them clean.

How many minutes do you usually steam seafood and shellfish?

The steaming time of seafood and shellfish is generally about ten minutes or more. At the same time, the steaming time should be adjusted according to the species and size. For example, the steaming time of abalone depends on the size of the abalone, and generally 8-10 minutes is the best. For freshwater shellfish such as razor clams and clams, 5 minutes is enough. Scallops need to be steamed for about 8 minutes.

The common method for cooking shrimps and crabs is steaming, which usually takes 10 minutes. Large crabs need to be steamed for about 15 minutes to half an hour.

For smaller seafood, such as clams, cockles, mussels, and conches, just steam them for 15 minutes.

Are shells living things?

The shell is the exoskeleton of a mollusk, a part of an organism, not a living thing. If there is a soft body inside the shell, then the shell and the body inside the shell together constitute a living thing. The shell is a calcified substance formed by the secretion of a special glandular cell of a mollusk to protect the soft part of the body.

The formation of shells is a biomineralization process, which is a process of molecular manipulation using a small amount of organic macromolecules as templates to form highly ordered combinations of organic materials.

The basic structure of the shell is mainly divided into three parts. The outermost layer is the cuticle composed of hard protein, the middle layer is the prismatic layer composed of calcite or aragonite crystals, and the innermost layer is the nacre.

In the geological sense, shells are the most common form of preserved fossils and are often used to determine the systematic evolution of geological formations, the exact age of strata, and the classification of shellfish populations.
