Daring to spoon jam (10)
I believe the answer is:
bottleneck
'jam' is the definition.
(I've seen this before)
'daring to spoon' is the wordplay.
'daring' becomes 'bottle'.
'to spoon' becomes 'neck' (I've seen this before).
'bottle'+'neck'='BOTTLENECK'
(Other definitions for bottleneck that I've seen before include "Congestion" , "Snarl-up" , "hold-up situation" , "Liquid is poured through it" , "Traffic restriction" .)
