Tell me about litchi tomatoes.
Another uncommon edible nightshade. Tall, gangly, indeterminate plants, with attractive deeply-lobed foliage, large conspicuous flowers, clusters of sweet red 1" berries - and numerous very sharp thorns on all green surfaces. The plant size & form is very similar to tomatillo, and should be supported to make it easier to avoid the thorns while harvesting. The plants will survive a frost down to 27-28 F. It bears rather late though, and the productivity is not very high given the amount of space taken up by those large plants. I don't grow many plants, so seldom have enough berries for anything other than snacking.
There is some variability in the genome, and the cultivar I grow (Morelle de Balbis) could probably benefit from breeding efforts, were anyone so inclined (which doesn't appear likely). Some of the plants have small berries (1" or less) that drop or release easily when ripe; some have larger berries (about 1.5") that cling tightly when ripe & often tear when pulled off. I'm not putting much effort into breeding, but do select for & save the largest berries.
The berries are completely enclosed within a thorny calyx, which peels back when ripe, exposing the fruit. They have rather large seeds, and a sweet cherry-like flavor that to me is reminiscent of gooseberry (as are the thorns). The flavor can vary with temperature. A few years ago, I had one plant whose berries had a peach-like flavor; and hoping to stabilize that one, I collected some of the berries for seed saving. Unfortunately, after mashing the berries to ferment them, I forgot about them, and all of the seed rotted.

I sure wish I had that opportunity to take back.
I once had photos of the mature plants, and the ripe berries... but apparently those were lost in a hard drive crash years ago. Had I realized, I would have taken new photos this year - ooops.

I do have a photo of the plants in bloom though:
This actually is a good bee plant. You can see some of the long & very sharp thorns; you wouldn't want to plant this where young children have access. It might be good for discouraging 2-legged thieves though.
