I had a few pieces of some extremely spicy beef jerky. (Blair’s Sudden Death Beef Jerky) Well, it was extremely spicy for me, anyway; I am sure it wouldn’t be too bad if someone was super into spicy foods. I like spicy food, but not over-the-top spicy like some people.
Anyway, the point is, I opened a bottle of cold Soylent 2.0 and it seemed to do a descent job of quelling the burn. Not perfect, mind you, but I think it did a better job than milk, which is the often-cited remedy to help with one’s spicy mouth.
