An experiment…

Plan:

1. Grate or dice quince (skin-on), weigh
2. Chop the same weight of rhubarb
3. Add lemon juice approx a large lemon to 1kg of “fruit”
4. Same weight of granulated sugar as fruit weight
5. Lemon zest?
6. Ginger?

Cook until set point.

Consider: boil up the quince cores and strain for extra pectin?
