Interested by your posting on physalis, as I have a small physalis plant in
my garden (30km east of London) that has produced lots of orange berries /
fruits.

Although the lanterns and fruits look very similar to those in Sainsburys
imported from Colombia ~ the ones from my garden continue to taste rather
bitter even when fully ripe.

I guess you could pick a few green physalis and try same method as for green
tomatoes ?
