Amount of fancy stiff upper lip, for starters (7)
I believe the answer is:
fistful
'amount' is the definition.
(fistful is a kind of amount)
'fancy stiff upper lip for starters' is the wordplay.
'fancy' is an anagram indicator.
'for starters' indicates taking the first letters.
The first letters of 'upper lip' is 'ul'.
'stiff' with letters rearranged gives 'fistf'.
'fistf'+'ul'='FISTFUL'
'of' is the link.
(Other definitions for fistful that I've seen before include "As much as can be held in the hand" , "amount of dollars?" , "Amount a hand holds" , "it should be within one's grasp" , "A -- of Dollars (film)" .)
