I finally cooked up my raspberries into syrup last night. I had maybe a cup and a half of wild raspberries, a quarter or half a cup of water, and part of a scoop of sugar (maybe a quarter cup, maybe more.) And maybe one tiny spider crawling around to get out of the hot water until I fished it out. I boiled it up, simmered it for a while, tried to crush the berries with a spoon, and drained it through a tea strainer. It’s a thin syrup, but definitely good over vanilla frozen yoghurt.
It only ended up being half a cup or so of juice. If I want to make raspberry jelly I’ll need six times as many berries. I don’t think there are that many to pick.
