Teases heavyweight, offering type of apple (7)
I believe the answer is:
ribston
'type of apple' is the definition.
'ribston' can be an answer for 'apple' (I've seen this before). I am not certain of the 'type of' bit.
'teases heavyweight' is the wordplay.
'teases' becomes 'ribs' (I've seen this in another clue).
'heavyweight' becomes 'ton' (a ton weighs a lot).
'ribs'+'ton'='RIBSTON'
'offering' acts as a link.
Can you help me to learn more?
(Another definition for ribston that I've seen is " Variety of apple".)
