Drinks to help the digestion of eats? (4)

I believe the answer is:

teas

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

'drinks' is the definition.
(tea is a kind of drink)

'help the digestion of eats?' is the wordplay.
'eats' anagrams to 'TEAS'.
But, I am unsure how the anagram is indicated.

'to' acts as a link.

Can you help me to learn more?

(Other definitions for teas that I've seen before include "Hot drinks" , "Afternoon meals" , "Beverage made by steeping leaves in water" , "Beverages from leaves" .)

I've seen this clue in the Evening Standard.
