Cold sweets oddly increase (4)

Ross

I believe the answer is:

ices

I'm a little stuck... Click here to teach me more about this clue!

'cold sweets' is the definition.
'ices' can be an answer for 'sweets' (ice is a kind of sweet). I am unsure of the 'cold' bit.

'oddly increase' is the wordplay.
'oddly' indicates alternate letters (letters in the odd-numbered positions are used).
The alternating letters of 'increase' are 'ICES'.

Can you help me to learn more?

(Other definitions for ices that I've seen before include "ecorates with frosting" , "Freezes" , "summer refreshment" , "Decorates cake with sugar topping" , "Decorates cakes with frosting" .)
