Wendy's Southwest Chipotle Dipping Sauce

I don't have the recipe but that sauce was the biznizz

I make a chipotle-mayonnaise sauce for my fish tacos. Mix about 1 cup of mayonnaise with a tsp of adobo sauce from a can of chipotle peppers in adobo sauce. Just use the sauce, not the actual peppers. And be careful, adobo is super spicy. I mix in a little and taste to check the heat level. Then add a little more if needed.

That picture has more red coloring than my suace. Maybe they put a tomato in a blender and then added it to the sauce. They also may have hydrated a dried red pepper (remove seeds before hand) (new mexico or red hatch), put in blender, then added to the sauce.
