I don't know what it tastes like. Ling hing mui is the closest I can get, you know, that sweet, salty taste in your mouth after it's gone? Especially if you were sucking it in a lemon. But it's kinda like saying a plum tastes like a peach. It's closer than anything else I can come up with but not very close.
But hey! Now I can say I've tried spiced cumin soda!
