Almost roar consuming last drop of spicy sauce (5)
I believe the answer is:
shoyu
'sauce' is the definition.
(I've seen this before)
'almost roar consuming last drop of spicy' is the wordplay.
'almost' means to remove the last letter (most of the word but not all of it).
'roar' becomes 'shout'.
'consuming' means one lot of letters goes inside another.
'last drop of' indicates one should take the final letters.
The last letter of 'spicy' is 'y'.
'shout' with its last letter taken away is 'shou'.
'shou' going around 'y' is 'SHOYU'.
(Another definition for shoyu that I've seen is " Sauce".)
