When I was a kid,Dad used to make wine from the berries of this plant:
It's called Agarita,also Texas Barberry. No pics of the berries,sorry. Too late in the year for that. But it was a serious chore picking enough for a batch of wine,since the berries are about the size of a pencil eraser. And the spines on the leaves aren't cactus tier,but they poke you.
The best way to pick the fruit involved kids (of which I was one),some gunnysacks,and some sticks.
You make the kids spread the gunnysacks on the ground under the bushes( some of those bushes get pretty big),and you have to make sure they know to watch out for copperheads and rattlesnakes.
Then you make the kids beat the bushes with sticks,so all the ripe berries fall off the bush and onto the gunnysacks.
Then you make the kids crawl back under the bushes and pull the gunnysacks out into the open,while being careful not to spill any of those berries.
Then you empty the gunnysacks into some kind of other container. ( usually any twigs,dead leaves,etc. will get stuck on the gunnysack,but if they don't have the kids pick them out) And you move on to the next bush.
Cooking some rice in a pot sounds a lot,lot easier.
