Makes an amazing Jam. Surprisingly complex flavour.
Yep - one of my favourite jams - that's how pretty much all my black currents are used.
And they have a naturally high content of pectin (a fibre that is used as a thickener additive / gelling agent).
You can still get UK blackcurrant yogurt (eg "Longley Farm") in the same little pots I used to get from the milkman in the mid-70s so not all is wrong with the world....
I didn't like it at first but as some grows in my garden I got used to it. Now eating blackcurrant while working is one of the highlights of summer for me.
Chokeberries would made an acceptable substitute.
If ever there were a food item that needed a "Chilean Sea Bass" style marketing rebranding, its the Chokeberry.
