It provides beer and some toasties (4)
I believe the answer is:
oast
'it provides beer' is the definition.
(kiln for drying hops)
'some toasties' is the wordplay.
'some' indicates the answer is hidden within the clue (some of the parts of the word are used).
'OAST' can be found hidden inside 'toasties'.
'and' acts as a link.
(Other definitions for oast that I've seen before include "Cooker" , "Kiln for drying hops or malt" , "Hop-drying kiln" , "Oven for hops" , "Hop-kiln" .)
