@tbendl Ok. I still measure in Imperial measurements. That's pounds and ounces.
8oz each of red, black, white currants.
8oz gooseberries
8oz cooked rhubarb drained.
11oz sugar, it's not sweet but you can change the sugar.
1.5 oz arrowroot for thickening.
Except rhubarb, Put rest of fruit and sugar in pan, in a separate dish add some water to arrowroot to make a paste,bring fruit and sugar to boil, then add arrowroot, as soon as it thickens take it off the heat. If you let it boil for too long it will go thin. Put in a dish to cool. When completely cool add the drained rhubarb. Then stir it in. I always drain the rhubarb in a seive. If you think that it's too thick,add 1oz of arrowroot instead of 1.5oz next time.
I don't know what measurements you use so hope that it's ok.
