Spread butane around in club (6,6)
I believe the answer is:
peanut butter
'spread' is the definition.
(I know that peanut butter is a type of spread)
'butane around in club' is the wordplay.
'around' indicates anagramming the letters.
'in' indicates putting letters inside.
'club' becomes 'putter' (a golf club).
'butane' anagrammed gives 'eanutb'.
'eanutb' going into 'putter' is 'PEANUT BUTTER'.
(Other definitions for peanut butter that I've seen before include "Leguminous spread" , "Spread made from groundnuts" , "something to eat" , "Golden brown paste" .)
