Fruit tree ID pls

[mnormand]

Another question for y'all...

When I was growing up in Avoyelles parish we had a medium size tree with scaly bark and stickers on branches. It produced a fruit about the size of a cherry tomato, but very similar to an apples texture. They were green, then turned red splotchy, and we'd start climbing and eating like crazy until they turned full red, then soft. We had bare feet like leather then, LOL. Dang tree looked like a bunch of monkeys with us perched up there feeding!

We called them ja jums best I can type... 50 years later and I never learned anything more about them.. Anybody?
