Managed OK with cracker -- cut another bakery item
'another bakery item' is the definition.
Although both the answer and definition are singular nouns, I can't see how they can define each other.
'managed ok with cracker cut' is the wordplay.
'managed' is an anagram indicator.
'with' says to put letters next to each other.
'cut' means to remove the last letter.
'cracker' with its last letter removed is 'cracke'.
'ok'+'cracke'='okcracke'
'okcracke' anagrammed gives 'ROCK-CAKE'.
Can you help me to learn more?
(Other definitions for rock cake that I've seen before include "Rough-looking hard bun" , "Baked tooth-breaker?" .)
