Onion Caviar

Renée G.


I have made and served this for so many years, I don't even remember where I happened to come by the recipe. I guarantee you there won't be any leftovers, so if you want some for yourself...might want to make a double batch. I will keep in the fridge for a week or maybe longer; we've never had it last longer.

How to Make Onion Caviar

  3. To serve, pour over a block of cream cheese and spread on crostini.
