First of all, buy some bananas!
Step 1: Bag your bananas. You can ripen bananas the same way banana distributors do: expose them to ethylene gas. Green bananas can be quite fibrous and to get the maximum nutrition and antioxidants from bananas you want them to ripen.
Step 2: Place the bananas you want to ripen in a paper or plastic bag with an unpeeled, uncut apple, pear, or tomato (or even another banana!). They will all emit ethylene gas as they ripen. Trapped inside the bag, the gas will accelerate the ripening process. Leave the bag in a warm, dry area to help aid the ripening process.
Step 3: Check the bag to see the progress. If the bananas are ripened, remove them from the bag. If not, leave them for another day. It should normally take about 24 hours to ripen this way. A ripe banana should be yellow with the occasional brown or black spot.
Step 4: Enjoy your tasty, sweet, fully ripe bananas!
Alternatively if you are looking to soften your bananas in under an hour (perhaps you want to use them for banana bread) try this easy method. It's not strictly ripening them, it's softening them, so it doesn't turn entirely green bananas sweet, they will need to be somewhat ripe to start with.
Step 1: Preheat the oven to Gas Mark 2, 300 degrees Fahrenheit or 150 degrees Celsius.
Step 2: Line a baking sheet with tinfoil or greaseproof paper. The bananas can make a mess and this will help!
Step 3: Pop the bananas on the baking sheet and put in the oven until blackened. Usually around 30-40 minutes although it can take longer if you've particularly large bananas.
Step 4: Remove and let them cool for 20 minutes and use! (Or don heavy duty gloves and squeeze out the banana beforehand, just be warned it's extremely hot!)
