Soya base with gnocchi and mint yoghurt starters promoted, we hear, presumably by Batchelors? (8)
I believe the answer is:
misogamy
'promoted we hear presumably by batchelors?' is the definition.
I can't judge whether this definition defines the answer.
'soya base with gnocchi and mint yoghurt starters' is the wordplay.
'soya base' becomes 'miso' (I can't justify this - if you can you should give a lot more credence to this answer).
'with' is a charade indicator (letters next to each other).
'starters' says to take the initial letters.
The first letters of 'gnocchi and mint yoghurt' is 'gamy'.
'miso'+'gamy'='MISOGAMY'
Can you help me to learn more?
(Other definitions for misogamy that I've seen before include "Hatred of marriage" , "dislike of unions" .)
