We get this question nearly every week, usually from someone looking at a plate of sweet plantains and trying to work out whether we fried a banana.
We didn't.
Related, not interchangeable
Plantains and bananas are cousins. Both belong to the genus Musa, and side by side they look like the same fruit at different sizes. But they're bred and used for completely different things.
| Banana | Plantain | |
|---|---|---|
| Eaten | Raw | Cooked, essentially always |
| Starch and sugar | Sugary when ripe | Starchy; sweetens slowly as it ripens |
| Skin | Thin, peels easily | Thick and tough; often needs a knife |
| Size | Smaller, curved | Larger, longer, more angular |
| Role on the plate | Fruit or dessert | A starch, like a potato |
The useful way to think about it: in Jamaica and across the Caribbean, a plantain is not fruit. It's a vegetable side.
Ripeness is the whole story
A plantain is a different ingredient at every stage, and the color of the skin tells you which one you're holding.
- Green — Hard and starchy, barely sweet at all. This is the potato stage: boiled, or sliced and fried twice into crisp tostones.
- Yellow — Softening, sweetening, still holding its shape. Good for frying, and a common everyday side.
- Yellow with heavy black spots — The sweet spot, literally. Soft, sugary, and caramelizes beautifully in a hot pan. This is what we use.
- Mostly black — Very sweet and very soft. Still good, but it'll fall apart if you're not careful.
A plantain that looks like a banana you'd throw out is a plantain that's finally ready. If you buy them green at the store, give them a week on the counter.
Why ours taste the way they do
Our sweet plantains are cut from ripe fruit and fried until the edges caramelize and the centers go soft. The sugar is the plantain's own. Nothing is added to sweeten them.
That's also why they work so well next to spicy food. Sweetness is one of the best things you can put beside scotch bonnet heat, which is why we tell people to order plantains with Jerk Chicken. Our heat guide goes further into that.
Green banana is a different thing again
To complicate it slightly: Jamaicans also cook green banana, which really is a banana, just picked and boiled while it's still hard and starchy. It turns up next to Ackee and Saltfish and in Saturday Soup. Same family, third use.
The short version
- Plantains and bananas are related, but you can't substitute one for the other.
- Plantains are cooked, not eaten raw.
- Black skin means ready, not spoiled.
- Get them with something spicy.
