3 min. First word is obvious; should've looked at 3rd word after the comma next (double letter at end). Also, the first word gives away three words which share letters with it.

Then get the word after the comma (only one or two possibilties, grammatically), and it falls into your hand.

Yeah, this one opens up like a ripe banana.

Yes. About 3 and 1/2 min. First word led to rest of JBZ prefix words. URR and then 3rd word after the comma. Rest of puzzle fell into place.
