Bananas are always the same shade of yellow. That’s a shame, because we’re missing out on a lot of flavour. But with a bit of know-how, we'll never have to be bored by yellow again.
"Ripening bananas is a very tricky process. It requires a lot of intuition" wrote Ursula Brunner in her book about the Banana Women's movement. She came to this conclusion after the Banana Women brought bananas to Switzerland for the first time in 1986.
At that time, the Banana Women were struggling with fruit that became brown too quickly or turned an ashen grey colour instead of bright yellow. Banana ripener Hans Roelli helped the women, explaining to them that bananas need to be carefully monitored while ripening.
So why can't bananas be harvested when ripe? Unlike most other types of fruit, bananas only ripen after they are harvested. If they are left on the plant, they burst and become mealy. That’s why the fruits are picked from the plant while they are still green. This also makes them easy to transport and it's the reason the tropical fruit is now widely available throughout the world.
We rarely find green bananas in supermarkets. The bananas on the shelves are always the same shade of yellow, perhaps with a sprinkling of brown spots. They are at the end stages of ripening and only account for a fraction of the banana's flavour spectrum.
Bananas can be more than just yellow and sweet, as three of our employees discovered. Each of them took home a crate of bananas from the Dominican Republic in November 2019. Green, unripe bananas. Their aim was to find out what they could do with the green fruit.
"It's not that hard to ripen bananas at home", they concluded. "But you have to expect the unexpected." For example, the bananas could all become ripe at once.
Which would of course be a problem if you had 18 kilos of them. But thanks to the work of our three guinea pigs, we now know how you can avoid this problem and what you need to watch out for.
Banana farmers in the Dominican Republic pack the bananas into a plastic bag without a protective atmosphere. The plastic bag is important because it keeps the fruit moist. High moisture levels stop the bananas from producing ethylene. The gas, which is also released by apples, kiwis, avocados and mangos, sets off the ripening process after harvesting. No gas, no unwanted ripening.
As long as the bananas are kept at temperatures between 13 and 14 degrees Celsius, they can be stored at home for two to three weeks. You should try not to let the temperature fall below 13 degrees, otherwise the fruit may be damaged by the cold and will not ripen at all. Instead, it will turn completely brown. But even these bananas, like the green ones, can still be used in savoury dishes.
The authors of Gartenjournal Magazine (German only) distinguish between seven different colour shades that you can use to determine the ripening stage of your bananas:
Keep these tips in mind and you'll become a successful banana ripener. Then you can bring your 18 kilos of bananas to the perfect stage ripeness, one batch at a time.
But you don't have to go to all that trouble if you want to use the bananas as a side dish in place of potatoes. All you'll need is firm, green bananas.
There are even entire dishes centred around green bananas. Like the green bananas used in Aji-Li-Mojili sauce. For instructions on how to prepare this northern Caribbean dish complete with photos, visit wikiHow: How to Cook Green Bananas. Or just boil them like Ras Mackab does.

If a lot of your bananas become too ripe, you can use them to make banana bread or cake. Most of these recipes call for overripe bananas. You'll find plenty of inspiration on the Epicurious website.
Last February, we received a test shipment of fresh bananas from the Dominican Republic. We ended up giving 3,600 kilograms of bananas to our customers! The experiment was a success, even though the bananas took quite long to ripen for many of our customers due to the colder temperatures. We're certain that with some practice, you'll be able to ripen bananas at home too. The green bananas are now available again for pre-order in our online shop!

Smallholders and local producers harvest and refine products of extraordinary quality worldwide. But for many of these producers there is no adequate or stable market. You can buy directly from these producers via the Access to Market Platform and help them to participate in the market. The principle behind this is crowd ordering – a new trade model whereby a number of consumers order a product together so as to achieve a minimum order quantity. We at gebana support the producers with our know-how, and organise the logistics.
Enable someone to make their first export with your order. Please note: Unexpected events often lead to delays, and you may find that the quality is not yet perfect. For this reason, your feedback is absolutely essential. The export experience and your feedback are important steps for the producers towards accessing the market. As a customer, you are witness to the whole process, playing your part in pioneering work.
You can order from these producers simply and directly. You receive your product as soon as the minimum order quantity has been reached and the products are ready. The risk for you is minimal, since the producers already have a product that is ready for market. This sales channel is beneficial to both the producers and the consumers, since it cuts out the middle man.
Be part of the development of supply chains and support innovation! Some of the ways you can do this include testing new products, giving feedback, or financially supporting the producers in their next steps. In doing so, you will be able to see for yourself how the products and supply chains develop.
This is where you can see all the completed projects on the Access to Market Platform at a glance. You can find out where products are now available from or whether the producers are still seeking a trade partner.
