A drop of IPA and I look around for a saucy type (5)

Ross

I believe the answer is:

aioli

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

'a saucy type' is the definition.
Although both the answer and definition are singular nouns, I cannot understand how they can define each other.

'a drop of ipa and i look around' is the wordplay.
'drop of' suggests taking the first letters (the smallest possible amount of the word).
'and' says to put letters next to each other.
'look' becomes 'lo' (archaic exclamation meaning 'look!').
'around' shows that the letters should be reversed in order.
The initial letter of 'ipa' is 'i'.
'i'+'lo'='ilo'
'ilo' in reverse letter order is 'oli'.
'a'+'i'+'oli'='AIOLI'

'for' is the link.

Can you help me to learn more?

(Other definitions for aioli that I've seen before include "Dressing" , "Garnish" , "mayonniase" , "Garlic 9" , "A lamb joint; driven clouds" .)
