I had no idea Mom used to throw away baby carrots with white stuff on them.

Rinse Them: A quick rinse under cold water can make them look more vibrant.
Soak in Water: Place the carrots in a bowl of water for a few minutes to rehydrate and restore their crisp texture.
Why Does It Happen?

Baby carrots are typically peeled and cut from larger carrots, which removes their natural protective layer. This makes them more susceptible to drying out when stored in less humid conditions. Proper storage can help minimize white blush:

Store baby carrots in an airtight container or resealable bag.
Keep them in the crisper drawer of your refrigerator to maintain moisture.

Perhaps this is why your mom wanted to make sure the carrots were always fresh and appetizing! If she had other food-related habits or tips, it might be fun to explore those too.

Baby carrots may get white blush from time to time, but with a little care, they’ll stay crisp and delicious. So, don’t toss them out—just refresh and enjoy!
