Soup that fills pot up Brando drained (5)
I believe the answer is:
gumbo
'soup' is the definition.
(type of Cajun soup)
'fills pot up brando drained' is the wordplay.
'fills pot up' becomes 'gum' (I can't explain this - if you can you should believe this answer much more).
'drained' means to remove the middle letters.
'brando' with its centre taken out is 'bo'.
'gum'+'bo'='GUMBO'
'that' acts as a link.
Can you help me to learn more?
(Other definitions for gumbo that I've seen before include "Spicy Cajun soup" , "Spicy soup; okra" , "Cajun chicken dish" , "Soup from Louisiana" , "Okra; spicy Cajun dish" .)
