Potato salad ingredient, for short (4)

I believe the answer is:

mayo

(Other definitions for mayo that I've seen before include "radio presenter" , "Saucy thing" , "Irish county -- salad cream" , "Cold, creamy sauce (abbr)" , "Irish county - sauce (abbr)" .)

I've seen this clue in The New York Times.
