"I mostly taste Honey mustard... I think. This is like the sandwich you make if you are lazy and all you have in your fridge are old condiments. It's not even really that bad, it's not unbearable, it's just so weird," Craggs said.
And really, he's right. Though it looks like your grandfather's 60-year-old and frequently used handkerchief, the taste is tingly, mushy, and really at the end of the day not even that awful. There's an overwhelming mustard taste to it, which leads me to believe HM is the most potent of all the Subway sauces. And it definitely has a burn to it. Like a lingering case of chlamydia... or so I assume.
