No matter how acidic lemons and limes are, they can still spoil just like other fruits. Signs such as brown spots appearing on the lemon peel or the fruit becoming soft and mushy indicate that the lemon's taste is about to change.
To avoid lemons spoiling quickly, you should know the following methods.
If you want to keep lemons fresh for a full month
Wrap the fruits carefully in an airtight bag to prevent air from entering, then store them in the refrigerator.
How to store lemons if you want them to ripen quickly
If you want the lemon you bought from the market to quickly change from unripe green to ripe yellow, place it somewhere in direct sunlight. It will ripen within 2 to 3 days.
If you store it at room temperature instead of in direct sunlight, it will take about a week to turn yellow.
How to store a lemon that has already been cut
Place the cut side face down on a plate so it doesn't come into contact with air, and store it that way. Alternatively, seal it tightly in a crisp bag so air cannot reach it, or you can store it in an airtight container.
When exposed to air, the lemon's juices can be lost due to oxidation.
If you want to keep a cut lemon for about 2 to 3 days, place it cut-side down on a plate and then put it in the refrigerator.
How to store lemon slices that have been cut into rounds
Everyone already knows that lemon slices can be used to beautifully garnish a drink when mixing a beverage. For those who don't want to cut slices right before mixing a drink and prefer to prepare them in advance, place the ready-cut lemon slices on an oil-absorbing paper towel without letting them touch each other. Then store them in the cold section of the refrigerator.
How to store leftover lemon juice
Don't store leftover lemon juice in a cup. If you store it in a cup, after several days both its taste and smell will spoil. That's why you should pour it into an ice cube tray and freeze it into lemon juice ice cubes for storage.
