I Am Eating Dark Green Leafy Vegetable, But I be Darned If I Know What it Is
That's Corchorus olitorius also known as jew's mallow or jute leaves or bush okra. It's widely eaten throughout Africa and Asia. You may recognize "jute" because the plant is also used to produce jute fibers that become rope and burlap among other things. The Ewe word is "ademe".
Terrific source of beta-carotene, iron. vitamin C plus some other vitamins and mineral. Caution: it turns into a big slimy mess when cooked.
Yes, I think you are describing it perfect. Ah Duh May - The one man kept telling me it is sticky, about as close to slimy as a Ghana man can talk. I do not care, I am eating the leaves, and I like the taste raw, but I am not going to eat much, so far I have not had a problem, with stomach, or toilet.
