When cooking purple potato porridge, to make it appear purple, you need to pay attention to the following points:
1 Use fresh purple sweet potatoes. Fresh purple potatoes contain more anthocyanins, and boiled purple potato porridge is more likely to appear purple.
2 Do not peel off the skin of purple sweet potatoes. The skin of purple potatoes is rich in anthocyanins, and if the skin is not peeled, the anthocyanins will better dissolve into the porridge, giving the purple potato porridge a purple color.
3 Do not add alkali when cooking porridge. The addition of alkali will cause a chemical reaction of anthocyanins in purple potatoes, causing the color of purple potato porridge to turn black or blue, affecting its aesthetics.
4 Master the heat and time of porridge. If it is cooked too thickly or too runny, it will affect the color and taste of purple sweet potato porridge. When cooking porridge, it should be boiled over high heat, and then slowly boiled over low heat to fully dissolve the anthocyanins in purple potatoes and make purple potato porridge appear purple.
5 Add some lemon juice or vinegar. The acids in lemon juice or vinegar can promote the release of anthocyanins, making purple potato porridge more purple. Thank you all for watching!
