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

I haven't cracked this one yet — but the brilliant team at Fifteensquared have:

A (from clue text) + first letter (a drop) of I [pa], then I + LO (lo! = look! = a call for attention) reversed (around). A sauce made from garlic and oil, or a garlic-flavoured mayonnaise.
