Tips
Tired of your delicious avocados turning brown way to quickly? We know that the delicious fruit isn’t cheap, so how can we keep them longer? Turn to lemons! Many people are aware that lemon juice can keep fruits and vegetables from browning – moms have been using lemon juice on apples forever! Lemons can do the same with avocados. Instead of squirting lemon juice on the avocado, though, just lay a slice of lemon on the open half of the avocado. Wrap it in saran wrap to make sure it stays, then throw it in the fridge! You’ve now successfully extended the life of your avocado! Feel free to invite me over if you’re making guacamole… ;-)
