When making French fries, cut the potatoes and put them in the refrigerator. Why do some people turn black the next day? Are they still edible?

After peeling potatoes, put them in water, add some salt to the water, and don't put them on the side, which is easy to oxidize and turn black.

Cut one and take out one, so that the potatoes won't be black.

After cutting the potatoes, you rinse them in water and rinse them several times to remove the starch from the potatoes.

You can also soak, but don't soak for too long or the weather will easily deteriorate, within an hour.

If you can't cook it on the spot, cook it or steam it and put it in the refrigerator, preferably frozen.

When you want to use it, take it out and fry it directly, or fry it in an air fryer with some salt or pepper.

Don't eat potatoes if they have a bad smell and a rotten heart in the middle. Don't eat potatoes when they sprout. To make matters worse, potatoes with long buds are poisonous.
