1/2 cup mayonnaise

1 tablespoon ketchup

2 tablespoons cream-style horseradish sauce

1/3 teaspoon paprika

1/4 teaspoon salt

1/8 teaspoon dried oregano

1 pinch ground black pepper

1/3 teaspoon cayenne pepper

This is the same sauce used with blooming onions, I just make my own but they do sell it in the store

almost like remoulade sauce,will try this..

It is close to it but has a bit more bite Zatarans sells a kit it has the onion cutter and a bottle of the dipping sauce and a package of the dry batter mix for the blooming onions, we also just cut the onion all the way through in quarters separate the pieces and batter and deep fry them , here they call those onion petals

yes my brother in law prepares those for us, when we visit.
