After being disappointed that there is not an actual Mayo Forum, I've started this thread for all things Mayo.
If I get a burger and the only sauce on it is mayo then I add ketchup to it.Let's talk mayo hybrids. I've already covered horsey sauce.
Other notable awesome Mayo combos:
-wasabi mayo (good with fish, sushi topping)
-hot sauce (pick your favorite) with mayo (excellent with fries, again good with sushi)
-old bay in mayo (fish sandwiches, crab cake sandwiches)
What else do you guys have?
