'dragons' den offer' is the definition.
Although both the answer and definition are singular nouns, I don't understand how one could define the other.

'a variety of peruvian cattle' is the wordplay.
'a variety of' is an anagram indicator.
'peruvian'+'cattle'='peruviancattle'
'peruviancattle' with letters rearranged gives 'VENTURE CAPITAL'.

Can you help me to learn more?
