Do purple potatoes stay purple when cooked?

The reason why purple potatoes are purple is mainly because purple potatoes contain a large amount of anthocyanins. Anthocyanins are water-soluble pigments and will change a little during the heating and cooking process, but the color change will not be very large.

But if the cooking time of purple potatoes is too long or the cooking temperature is too high, then the color of purple potatoes may become lighter further, and even turn yellow or brown.

How do you know when purple potatoes are ready?

You can judge whether purple potatoes are ripe by the following methods:

First, poke with chopsticks or toothpicks. When boiling or steaming purple potatoes, when the time is almost up, take a chopstick or toothpick and gently prick the purple potato. If it can be easily inserted all the way to the center part without obvious resistance, then it means it is cooked.

Second, observe the appearance. If it is boiled purple potatoes, when its skin begins to crack a little or the color becomes a little darker, this may be a sign of being cooked. If it is steamed purple potatoes, the surface will become relatively soft. When gently pressed, you can feel that it is no longer hard.

Third, judge from the taste. If you are not sure if it is cooked, you can take a small piece and taste it first. The cooked purple potato has a soft and glutinous taste. There is no stiff feeling. It is easy to chew and there is no raw taste of starch.

Are purple potatoes healthier than white potatoes?
