Avocados are a versatile fruit with a range of health benefits, but finding a ripe avocado is not always easy. There are several methods to ripen avocados quickly, including using a paper bag with other fruit, an oven, or a microwave. The paper bag method works by exposing the avocado to ethylene gas, which is a compound that signals to the fruit that it should ripen. A plastic bag, however, may not be a suitable replacement for a paper bag as it is not breathable and can trap too much moisture, causing the avocado to rot before it ripens.

Plastic bags trap moisture, causing avocados to rot before ripening
While it is possible to ripen avocados in a bag, it is best to avoid using plastic bags. Plastic bags trap moisture, causing avocados to rot before ripening.
Avocados produce ethylene gas, a plant hormone that triggers the ripening process. The ethylene gas is trapped by using a paper bag, which holds it close to the fruit and helps it ripen faster. However, plastic bags are not breathable and will trap too much moisture, causing the avocado to rot before it ripens.
To ripen an avocado quickly, place it in a paper bag with a banana, apple, or kiwi. These fruits also emit ethylene gas, so when paired with an avocado inside a paper bag, the ethylene becomes more concentrated, and the avocado ripens faster. If you don't have any of these fruits, you can also fill the bottom of the bag with about 2 inches of flour. The flour absorbs excess moisture while helping to trap ethylene, resulting in a perfectly ripe avocado.
If you're in a hurry, you can also ripen an avocado in the oven or microwave. However, these methods will compromise the taste and texture of the avocado. For the oven method, wrap the avocado in foil and bake at 200°F, checking every 5 to 10 minutes until it reaches the desired softness. For the microwave method, cut the avocado in half, remove the pit, and wrap each half in plastic wrap. Microwave in 30-second intervals on medium-high until it reaches the desired softness, then submerge the wrapped halves in ice water to stop the cooking process.

Paper bags are better as they allow ethylene gas to concentrate
Avocados can be ripened by placing them in a paper bag with other fruit, such as apples, bananas, or kiwis. These fruits release ethylene, a plant hormone that aids in the ripening process. The paper bag traps the ethylene gas, causing it to concentrate around the avocado, which helps it to ripen faster.
Paper bags are better than plastic bags for ripening avocados because they allow ethylene gas to concentrate. Plastic bags are not "breathable" and will trap too much moisture, causing the avocado to rot before it ripens. The paper bag method can also be enhanced by placing the bag in a warm spot, as warm fruit ripens faster.
If you don't have any apples, bananas, or kiwis, you can still ripen an avocado in a paper bag by itself. The avocado will produce ethylene gas on its own, and the paper bag will trap the gas, causing the avocado to ripen faster than if it were left out on the counter. This method may take a bit longer than using other fruit, but it will still be effective.
For best results, seal the paper bag tightly to prevent ethylene gas from escaping. Check the avocado daily until it reaches the desired level of ripeness. Depending on the initial firmness of the avocado, this process can take anywhere from overnight to 48-72 hours.
In addition to fruit, some people recommend adding a scoop of flour to the paper bag. The flour helps to absorb excess moisture and trap ethylene gas, resulting in a perfectly ripe avocado with a creamy texture and no brown spots.

Avocados produce ethylene gas, aiding the ripening process
Avocados produce ethylene gas, which is a natural plant hormone that acts as a signalling molecule. This gas triggers a series of biochemical changes in the fruit, including the breakdown of complex carbohydrates into simple sugars, resulting in the softening of the fruit's flesh and the development of its characteristic flavours and aromas. As the avocado ripens, it produces more ethylene gas, which speeds up the ripening process.
To accelerate the ripening process, you can place an avocado alongside ethylene-producing fruits like bananas or apples. These fruits will produce ethylene gas when ripe, triggering the ripening of the unripe avocado. This method involves exposing the avocado to the ethylene gas produced by the other fruit.
Another popular method to speed up ripening is to use a paper bag. Placing an avocado in a paper bag with an ethylene-producing fruit like an apple or banana will create an enclosed space that traps the ethylene gas, concentrating it around the avocado and promoting faster ripening. The paper bag method is preferred over using a plastic bag because plastic is not breathable, and it will trap too much moisture, causing the avocado to rot before it ripens.
Additionally, temperature plays a crucial role in the ripening process. Avocados prefer a temperature range of 60 to 68°F (15 to 20°C) for optimal ripening. Lower temperatures slow down the process, while higher temperatures can accelerate it. Extreme temperature fluctuations can negatively affect the quality of the fruit.
Once the avocado has ripened to your desired level, it can be stored in the fridge to prolong its shelf life. Refrigeration slows down the ripening process by inhibiting the avocado's natural enzymes. However, refrigeration can affect the texture of the avocado, making it firmer than desired.

Ripe avocados should be stored in the fridge to slow ripening
Avocados are a tricky fruit to manage, as they seem to turn from unripe to overripe in a matter of hours. The window of time in which to eat a perfectly ripe avocado is very short. There are several methods to ripen avocados faster, such as placing them in a paper bag with ethylene-producing fruits like bananas or apples, or wrapping them in newspaper. However, once they are ripe, it is best to store them in the fridge to slow down the ripening process and extend their shelf life.
Ripe avocados, if stored at room temperature, will only last one to three days. If stored correctly in the refrigerator, they can last up to a week. The crisper drawer is the best place for them, as it is slightly warmer than the upper shelves. If you don't have a crisper drawer, simply place the avocados in a cool spot in the kitchen, such as a pantry, ensuring they are not touching or stacked to avoid bruising.
It is important to note that avocados will continue to ripen in the fridge, just at a slower pace. If you are not planning to eat them for a while, it is best to purchase slightly unripe avocados and let them ripen at home. This way, you can control the ripening process and use the avocados when they reach the desired level of ripeness.
There are several other storage methods to keep ripe avocados fresh for longer. One method is to submerge whole avocados in cool water and place them in an airtight container in the refrigerator. However, this method has been deemed unsafe by the U.S. Food and Drug Administration due to the risk of bacterial growth. Another method is to brush the avocado flesh with lemon or lime juice, which helps minimise exposure to air and slows down browning caused by oxidation.

Using an oven or microwave to ripen avocados affects their taste and texture
While it is possible to ripen avocados in an oven or a microwave, it is not recommended as it affects their taste and texture.
The oven method involves wrapping the avocado in aluminium foil and baking it at 200 degrees Fahrenheit for 10 minutes. The cooking time can be extended by 10 to 15 minutes if the avocado is not soft enough. However, this method does not actually ripen the avocado but rather softens it, and the taste remains the same. The avocado may also become slimy in texture.
Microwaving an avocado can slightly soften it, but it does not mimic natural ripening. The avocado will not have the same fresh, buttery, creamy, or nutty taste as a naturally ripened avocado. Instead, it will retain an unripe taste with a smoother texture. Additionally, there is a risk of the avocado exploding in the microwave if it is not properly ventilated by piercing the skin with a fork or toothpick.
To naturally ripen an avocado, it is recommended to use a paper bag, which traps ethylene gas, a plant hormone that triggers the ripening process. This method allows the avocado to develop its characteristic fresh, buttery, nutty flavour. For faster ripening, the avocado can be placed in the paper bag with ethylene-producing fruits such as apples or bananas.
