Grill, with hesitation, US dough bread (12)
I believe the answer is:
pumpernickel
'bread' is the definition.
(pumpernickel is a kind of bread)
'grill with hesitation us dough' is the wordplay.
'grill' becomes 'pump' (I've seen this in other clues).
'with' is a charade indicator (letters next to each other).
'hesitation' becomes 'er' (sound used when hesitating).
'us dough' becomes 'nickel' (term for US 5 cent coins - 'dough' is money).
'pump'+'er'+'nickel'='PUMPERNICKEL'
(Other definitions for pumpernickel that I've seen before include "Slightly sour German black bread" , "Coarse dark rye bread" , "German ryebread" , "German coarse rye bread" , "Coarse ryebread" .)
