Spiritualist gets hard to find steak cooked thus (6,4)
I believe the answer is:
medium rare
'steak cooked thus' is the definition.
I don't know anything about this answer so I can't judge whether this works.
'spiritualist gets hard to find' is the wordplay.
'spiritualist' becomes 'medium' (synonyms).
'gets' means one lot of letters go next to another.
'hard to find' becomes 'rare' (I've seen this in another clue).
'medium'+'rare'='MEDIUM-RARE'
Can you help me to learn more?
(Other definitions for medium rare that I've seen before include "not to be grilled too much" , "not well done" .)
