Chances are good that you already have in your refrigerator the two ingredients required for making the best condiment known to humanity: sriracha sauce (sometimes also known as rooster sauce) and mayonnaise.
Combine them, in amounts of your choosing, and you will create instant flavor heaven. It is glorious on french fries (if you don’t believe me, check it out at Good Stuff Eatery) and on roast beef sandwiches. It perks up bland vegetables and is what gives a spicy tuna roll its kick. Lately I’ve been using it on crunchy roasted broccoli, but there are really no limits. I imagine it would be killer on a crabcake, or even as a binder, instead of plain mayo, in tuna salad.
I’m sure there must be some kind of food that doesn’t taste better with this on it, but I haven’t found it yet.
