I got the concept. I dont like mayo or ketchup tho. Too sweet. It's spicy mayo. I read a whole thing about mushroom ketchup once. it'd fpr the umami. Im just not a fan of mayo,
Vinagrette and mustard are the preference. I love whole grain mustard. Mexicans always want to sauce everything though. They also dont like it spicy despite tropes. Thais probably like it hottest. I had green curry yesterday for dinner yesterday and I asked for "thai spice" it's basically like getting pepper sprayed,. Meanwhile these girls are freaking out over jalapenos.
