How to prevent sliced apples from turning brown

Certified food scientist Jessica Gavin says the secret to fresh apples lies in how you cut them.

In one of her videos on TikTok, she demonstrates an easy method that prevents the fruit from turning brown for a long time.

All you need to do is make a slice down from the top, away from the stem. Rotate the apple and cut it similarly on all sides to give a “checkerboard pattern.”

Jessica explains that the pulp turns brown due to oxidation, so it is essential to keep the slices pieces together until they are eaten.

She suggests wrapping the entire sliced apple in plastic wrap to keep the shape intact and avoid any contact with the air that results in browning.

More essential chopping hacks

The food scientist’s channel is full of useful cooking hacks with a series of videos dedicated to the art of cutting fruits and vegetables.

In another video, Jessica shows an easy way to cut broccoli that stops the florets from breaking and falling apart.

She says you can minimize the mess by simply making a crosswise cut down the stock of the vegetable, but not cutting all the way through.

Use your hand to pull the stems apart for smaller florets. you can later cut them into finer pieces without creating a mess.

Jessica has a tip for cutting a butternut squash too as the skin is too thick for the knife to easily get through.

The simple technique involves “gently rocking the squash back and forth on the cutting board” while holding the knife in the shape position. She shows the knife easily slides down the flesh due to friction.
