A potato's cell walls contain pectin, and these pectin chains remain stable when they come into contact with acids. This means that potatoes will remain hard if they are in a dish that has a lot of acid (for example, a dish you've added wine to). Salt is needed to dissolve these pectin chains. 2 сент. 2019 г.
Why do some potatoes stay hard when cooked?
Potatoes that are still hard after baking haven't had a high enough heat for long enough to soften the starches in the flesh. Cooking for 15 minutes longer or pre-cooking in the microwave should soften the potato. You may need to check your oven temperature if it is faulty.
Why won't my potatoes get done?
If your potatoes are soft on the outside but still undercooked in the middle, the likely cause was cooking them at too vigorous of a boil. The potatoes may appear soft on the outside, which cooks at a fast rate, while the inside is not done cooking. Potatoes should be boiled at a simmer (i.e. a very gentle boil).
Why are my potatoes taking long to cook?
Potatoes take a long time to cook because they are very dense vegetables, and they are full of starch. The heat does not travel into the potato very quickly, and the center takes a long time to heat up. Until they get hot, potatoes will not cook.
Why are my potatoes taking so long to bake?
The oven is too hot. Low and slow—that's the mantra of the Perfect Baked Potato. If you've got the time to spare, cook the potatoes at 300°F for 90 minutes. If you need to speed that up, bump it to 450°F for 45 minutes. (Note: Your baking time will vary depending on the size of your potato and how hot your oven runs.)
