It's well-known that if you eat spicy food, you can neutralize the flavor (and thus stop your mouth from burning like a forest fire) by drinking milk. This is due to casein. Simply drinking water or something cold does not achieve the same effect.
But I'm vegan, so I don't drink milk. So what else can I consume (that's vegan) to quickly neutralize spicy flavors?
This is not a duplicate of How can I wash down spicy food?, as the advice there concentrates on dairy products.
