Seasoned dips served up round church (6)
I believe the answer is:
spiced
'seasoned' is the definition.
(spicing is a kind of seasoning)
'dips served up round church' is the wordplay.
'served up' says the letters should be written in reverse.
'round' indicates putting letters inside.
'church' becomes 'CE' (abbreviation for Church of England).
'dips' backwards is 'spid'.
'spid' going around 'ce' is 'SPICED'.
(Other definitions for spiced that I've seen before include "Flavoured with such as nutmeg" , "was over-scrupulous" , "Flavoured with additives from plant substances or seeds" , "hot, with reference to food" , "Flavoured with, eg, mace" .)
