Sunchokes are also called Jerusalem artichokes, so yes, they are the exact same things. Sunchokes, or Jerusalem artichokes, are an edible tuber that grows underground, much like a potato.

Anchovies, which is also known as Netholi / Kozhuva / Chooda / Podi meen is a small fish which is a cheap source of protein and is popular in Kerala. This fish's bone / meen mull is so soft, that we can even eat it along with its meat. Whenever I buy anchovies, I used to make peera pattichathu and also anchovies fry with it.
