Hotter or more piquant (7)

I believe the answer is:

spicier

I believe this is a double definition.

'hotter' is the first definition.
('spicy' can be a synonym of 'hot')

'more piquant' is the second definition.
('spicy' can be a synonym of 'piquant')

(Another definition for spicier that I've seen is " Hotter".)

I've seen this clue in The Times.
