Dance movement attempt makes one puff, perhaps (6)
I believe the answer is:
pastry
'one puff perhaps' is the definition.
(puff is a kind of pastry)
'dance movement attempt' is the wordplay.
'dance movement' becomes 'pas' (I've seen this before).
'attempt' becomes 'try' (synonyms).
'pas'+'try'='PASTRY'
'makes' is the link.
(Other definitions for pastry that I've seen before include "Dough of flour, water and shortening" , "Cake - tart" , "Choux --; puff --" , "Piecrust; small cake" , "Kind of baked food" .)
