Yoga — mostly pain that could be delicious (7)
I believe the answer is:
yoghurt
'delicious' is the definition.
The definition and answer can be both things that one consumes for nourishment as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'yoga mostly pain' is the wordplay.
'mostly' means to remove the last letter.
'pain' becomes 'hurt' (hurt is a kind of pain).
'yoga' with its last letter taken off is 'yog'.
'yog'+'hurt'='YOGHURT'
'that could be' is the link.
Can you help me to learn more?
(Other definitions for yoghurt that I've seen before include "Food from fermented milk" , "Healthy food" , "Fermented milk product" , "Bacteria-treated milk product" , "culture" .)
