galley; ship's kitchen
Rare, obsolete term for a ship's kitchen. Modern Japanese would use 船内調理室 or ギャレー.
In old naval documents, the word 烹炊所 is used to refer to a ship's kitchen.
Compound of 烹 (cooking) + 炊 (boiling/steaming) + 所 (place). The exact historical derivation is uncertain; it appears to be a coined term for a ship's kitchen, now obsolete.
