FAQs
You asked an excellent question, poking or piercing the potato too far in advance will result in discolored or gray where the utensil went into the potato. If doing for the next day, I'd probably just wash the potatoes and leave on the counter, covered with a clean towel.
How do you keep cooked potatoes from turning gray? ›
To keep peeled whole or cut potatoes white, cover them with cold water until you are ready to use them. If you are going to boil them, you can simply do so once you're done getting them ready. For other uses, drain the potatoes and pat them dry before cooking them.
Should I pierce my baked potatoes? ›
"Yes, it's good to prick them," Smith told Food52. "It pokes holes in the skin, which allows steam to escape. Otherwise, they could explode—it doesn't happen all the time, but it happens every once in a while.
Why is my baked potato GREY? ›
A: The potatoes were stored improperly for them to last that long after baking. Also, was there any chance that the potatoes were pierced with a fork to release steam or cut before baking? Those exposed surfaces, especially when wrapped tightly in foil and heated will become oxidized and turn brown or gray.
What happens if you don't poke a hole in a baked potato? ›
Rumor has it that an un-pricked spud will explode in the oven—but in all actuality, that's unlikely. Conventional wisdom says that when you bake a potato, you have to prick it with a fork all over a few times, piercing the skin to allow steam to release.
How do you keep cooked potatoes from turning black overnight? ›
Store the water-covered potatoes in a bowl in the refrigerator until you're ready to use them, up to one day in advance. For a little extra insurance, add something acidic to the water, such as a splash of vinegar or fresh lemon juice. This will help slow the oxidation process even more.
Is it better to bake potatoes covered or uncovered? ›
"I see a lot of people using foil to wrap their potatoes in but this is a big no-no and causes soggy skins!" he says. Foil holds in moisture and steams the potatoes, resulting in a "boiled" taste and texture. Plus, without the use of foil, the skin will get extra crispy and flavorful.
Do you eat a baked potato with a spoon or fork? ›
A baked potato depends on what part of the potato you like. I generally scoop out the middle with a fork or a spoon and then use a knife to cut up the peel afterward, but if I eat the whole thing together, then I start with a knife and fork.
Why should you poke holes in baked potatoes when cooking in the microwave? ›
These little holes allow steam to escape while the potato is cooking. Forget to poke, and your potato could end up exploding in your microwave from the pent-up steam. It's both messy and a serious dinner let-down.
What are the grey bits in potatoes? ›
This sounds like it is a chilling injury, which will show grey lines of discoloration. If the lines are very distinct and brown in color, then the potato may have zebra chip. Either one will be okay to mash and eat. However, both will oxidize quickly and cut and boil soon.
Raw potatoes should be firm to the touch with tight skin that's free of large bruises, black spots, or other blemishes. If a potato has become soft or mushy, you should throw it out. Though it's normal for potatoes to smell earthy or nutty, a musty or moldy odor is a hallmark of spoilage.
Can you reverse potato oxidation? ›
As we've mentioned, lemon juice and Vitamin C can slow down or even reverse oxidisation – but metal dishes can accelerate it. Rather than using cast iron, aluminium, or other metal containers for your potatoes, cook them or serve them in a glass or ceramic dish.
Do baked potatoes need to be pricked before baking? ›
The golden rule of baked potatoes? Always prick your spud! The old adage of them exploding under the pressure of oven heat is actually true. As the potato cooks, the skin acts as a seal, trapping water that expands the spud and steams during cooking.
Why do you put aluminum foil on baked potatoes? ›
Some say wrapping baked potatoes in aluminum foil helps them cook faster (aluminum conducts heat, then traps it), and it does keep them hot for longer once they come out of the oven, which is why we think restaurants use this method. Wrapping potatoes will also give you a softer, steamed skin, if that's what you like.
How deep to poke holes in baked potato? ›
A: Poke the potatoes with a fork just enough to pierce the skin so the potato won't burst when baking, especially in the microwave. Four or five times should be plenty. A potato is composed mainly of water, so poking them helps release steam as it cooks.
Why are my mashed potatoes turning grey? ›
A: Unfortunately, the potatoes reacted to being exposed to air by turning gray. When first cutting up a potato, we recommend that you place the pieces immediately into a solution of water and something acidic such as a tablespoon of concentrated lemon juice to a gallon of water.
How do you remove oxidation from potatoes? ›
No. Browning of the potato is caused by oxidation, and cannot be undone, much like with cut apples. To prevent your potatoes from browning when cut, you can submerge them in water, or use a chemical such as lemon juice to prevent oxidation.
How long can you leave potatoes in water before cooking? ›
The larger the potato pieces, the longer they'll last in water. If you're prepping with smaller pieces, don't soak for more than 12 hours. This trick is handy, but it'll only work for about 24 hours — so don't prep too far in advance.
Why do potatoes go black once cooked? ›
After-cooking darkening is caused by the oxidation of the ferri-chlorogenic acid in the boiled or fried potatoes. The severity of the darkening is dependent on the ratio of chlorogenic acid to citric acid concentrations in the potato tubers. Higher ratio normally results in darker tubers.
