dunno – i don’t use exact proportions. put mayo in bowl, slowly add the cayenne pepper sauce till it’s the consistency you’d like. then add garlic and sugar to taste.
mchemtob – it will probably taste similar. the garlic and sugar should taste like the ketchup. the only difference is that ketchup usually has high fructose corn syrup in it. BTW, you should check your mayo – some of them also have high fructose corn syrup inside.
