Up ante, cunningly, with creamy spread! (6,6)
I believe the answer is:
peanut butter
'up ante cunningly with creamy spread' is the definition.
'peanut butter' can be an answer for 'spread' (peanut butter is a kind of spread). I'm not certain of the 'up ante cunningly with creamy' bit.
'up ante cunningly with creamy spread' is the wordplay.
'cunningly' indicates an anagram (a cunning or tricky form of the letters).
'with' is a charade indicator (letters next to each other).
'creamy spread' becomes 'butter' (butter is a spread. I am not sure about the 'creamy' bit.).
'up'+'ante'='upante'
'upante' anagrammed gives 'peanut'.
'peanut'+'butter'='PEANUT BUTTER'
Can you help me to learn more?
(Other definitions for peanut butter that I've seen before include "Spread made from groundnuts" , "Leguminous spread" , "Golden brown paste" , "something to eat" .)
