When your mouth is coated with ma la, water tastes like flat ginger1 ale. One Sichuan devotee I know describes the ma la sensation as a tonguegasm. The pulse increases and the pupils dilate2, often accompanied by a postnasal drip. The brain floats in a euphoric ether.
当口腔里充满麻辣的滋味，清水品尝起来就像是姜汁饮料一样。我认识的一个川菜喜好者说，麻辣的感觉就像舌尖上的高潮，能叫你脉搏加快，瞳孔扩大，总是还会叫你流鼻涕，叫你的大脑在一个充满幸福的空间里飘荡。
