Kashrut
Among the numerous laws that form "kashrut" are prohibitions on the consumption of certain animals (such as pork and shellfish), mixtures of meat and milk, and the commandment to slaughter mammals and birds according to a process known as "shechita". There are also laws regarding agricultural produce that might impact the suitability of food for consumption.
Saraswat cuisine
Most Saraswat Brahmins are pesco-vegetarians. The inclusion of fish in the diet is not looked upon as non-vegetarian. Legend has it that when the Saraswati River dried up, the Saraswats who could not farm were permitted to eat sea food/fish. The fish were euphemistically called "sea vegetable" or झळकें from ( जल काय -Jal Kaay). Oysters, for example, are sometimes called "samudra phalam", or "sea fruit".
