French ready with enthusiasm to dismiss a German cracker (7)
I believe the answer is:
pretzel
'german cracker' is the definition.
(type of German snack)
'french ready with enthusiasm to dismiss a' is the wordplay.
'french ready' becomes 'pret' ('ready' in French).
'with' is a charade indicator (letters next to each other).
'enthusiasm' becomes 'zeal' (zeal is a kind of enthusiasm).
'to dismiss' indicates named letters should be taken away.
'zeal' with 'a' removed is 'zel'.
'pret'+'zel'='PRETZEL'
(Other definitions for pretzel that I've seen before include "Glazed, salted and twisted cracker" , "Curly savoury snack" , "Salted biscuit, shaped like a knot" , "Crisp salted biscuit" , "Curly savoury biscuit" .)
