Up-and-coming épicerie that is missing a few ingredients? (6)
I believe the answer is:
recipe
'up-and-coming epicerie that is missing a few ingredients?' is the definition.
I can't tell whether this defines the answer.
'up-and-coming epicerie that is missing' is the wordplay.
'up-and-coming' says the letters should be written in reverse.
'that is' becomes 'ie' ('i.e.' can be a synonym of 'that is').
'missing' is a deletion indicator.
'epicerie' with 'ie' taken out is 'epicer'.
'epicer' reversed gives 'RECIPE'.
(Other definitions for recipe that I've seen before include "Ingredient list" , "Chef's instructions" , "Kitchen directions" , "Cook's instructions" , "A baking formula" .)
