vanilla-yuzu poached quince, I simmered it down to make a bit of jelly. And I do mean, a bit. A wee bit.
After topping off my jars of poached quince, I strained the liquid through a mesh and had about 2 C left. I added 1/2 C organic granulated sugar and the vanilla bean. I brought it a boil and boiled rapidly until setting point is reached, about 15 minutes. As the liquid cooks, it will turn from golden to a rosy, apricot color.
I ended up with about 1/2 a cup of jelly. Next time I'm going to have to set out to make jelly...versus making jelly from leftovers!
