Signature Boom Boom Sauce, and where to source it

Give it a ketchup backbone under the sweet chili. That spoon of ketchup is what separates boom boom from plain bang bang — it deepens the color and adds a tomato tang that reads as its own thing.

Straight Answers
Can you freeze Signature Boom Boom Sauce? — Not ideal

Not really — the cream, custard, or emulsion turns grainy or splits once thawed. This one is best kept fresh in the fridge.

Can you make Signature Boom Boom Sauce ahead of time? — Yes

Yes — it keeps in the fridge for several days; stir or shake it before serving.

Is Signature Boom Boom Sauce gluten-free? — Yes

Yes — nothing in this recipe as written contains gluten. As always, glance at the labels on any packaged items (broth, sauces, chocolate), since brands vary.

Is Signature Boom Boom Sauce vegan? — Vegetarian, not vegan

It’s vegetarian but not vegan as written — it has egg. Make it vegan: a flax or aquafaba egg for the egg.
