The hawthorn is cleaned, half cut open, blackheads, tail stalks, and the seeds are smashed. This is the hardest work. I spent an hour throwing the flesh of the hawthorn into the soymilk machine, choosing the whole bean soymilk pattern, etc. The soya-bean milk machine will smash you, then boil it again and again. After 20 minutes, the mountain syrup will be ready.
