Beautiful cactus blooms, AG.
Luv, spicy mustard mayo is my own recipe, no real measurements. I put it in a ketchup squeeze bottle, holds about 1-1/2 cups. Put Best Foods mayo in a container large enough to mix in, add mustard to taste, whatever kind you like, a little or a lot, add onion powder, freshly ground black pepper, cayenne pepper, green chile pepper, few drops of green habanero sauce, and I have a blend of homemade hot chile peppers that I dried and ground myself, different colors so that shows up in the mayo, looks nice.You can make it as hot as you like, whisk it all together and put in squeeze bottle, hope you like it.
It is great on most vegetables, I like it on my hamburger and hotdogs too..
