How To Stop Avocados From Browning
Avocados are delicious, but if you leave them cut and exposed to the air for too long, all of that delicious green flesh starts to turn brown. To prevent this from happening, spray the cut side of your avocado with cooking oil to create a barrier between the avocado and the air.
You can also use this trick on guacamole. Spray the top of the guac with cooking oil so it doesn’t turn brown.
