Hoping to relieve pressure, cooked around 200 dumplings (7)
I believe the answer is:
gnocchi
'dumplings' is the definition.
(I've seen this before)
'hoping to relieve pressure cooked around 200' is the wordplay.
'to relieve' indicates named letters should be taken away.
'pressure' becomes 'p' (abbreviation).
'cooked' indicates an anagram.
'around' is an insertion indicator.
'200' becomes 'cc'.
'hoping' with 'p' taken out is 'hoing'.
'hoing' is an anagram of 'gnohi'.
'gnohi' placed around 'cc' is 'GNOCCHI'.
(Other definitions for gnocchi that I've seen before include "Dough" , "that is eaten" , "Flour, semolina or potato dumplings" , "Italian potato dumplings" , "Italian dumpling made of potato, flour or semolina" .)
