Lumpy mashed potatoes generally indicate undercooked potatoes. If you get to this point and realize you've undercooked your potatoes, just add a little bit of milk or cream, then cook the potatoes over low heat until the lumps begin to soften.
Here's how to do it: For every pound of potatoes in your mash, drizzle 1 tablespoon of melted butter over the dish and fold it gently into the potatoes. If the mash is still too gluey for your liking, repeat the process with another tablespoon of butter.
As already discussed, pastiness is caused by too much potato starch being worked into the mashed potatoes. The main way we combat this problem is by rinsing away starch, both before and after cooking potatoes for fluffy mashed potatoes.
Cook them a little longer. If they are baked potatoes, pop them in the microwave for 3 minutes. If they are boiled, leave them for another five minutes.
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.
Here's how to do it: Just prick a few holes in a few potatoes with a fork, and microwave on high for 3-4 minutes, turning over once. There you go—super-fast par-cooked potatoes.
You shouldn't let butter be the only dairy you use, however. Consider adding half-and-half or heavy cream and a bit of sour cream (even goat cheese) to get the best flavor and creamiest texture every time, like in these Best Mashed Potatoes.
If you find your mashed potatoes are soupier than normal, it's likely because you overcooked them, Buzzfeed says. Overcooked potatoes aren't always dry and hard, as it's possible to overboil a potato too. When you do so, more water is absorbed by the potato.
But the most essential suggestion, per Bon Appétit, is always to salt the water you are boiling your mashed potatoes in. It acts as pre-seasoning, and Bon Appétit recommends adding a full cup of kosher salt to the boiling water.
But if you've made them a little too runny for your taste, don't worry! You don't have to throw them out just yet. To thicken mashed potatoes, you can add a thickening agent like cornstarch, flour, powdered milk, or tapioca. Add one tablespoon at a time until you reach your desired consistency.
Empty the cold mashed potatoes into a medium saucepan or Dutch oven and set over low heat. Cover the potatoes and stir them occasionally until they are completely warmed through and smooth.
Once mashed potatoes reach the glue stage, there's no going back. Your potatoes may taste fine, but the thick, gloppy texture could be more than your guests can stomach.
As The Kitchn explains, potatoes will release starch when they're mixed and mashed. Once there is too much starch in your mashed potato mixture, the texture will quickly turn from fluffy to gummy.
You may think the dish is ruined, but don't fret. Here's a tip on How to Fix Over Boiled Potatoes. Drain the potatoes and place them back into the pot over medium heat and stir them. Stirring removes the excess water and dries them out.
CREAMED MASHED POTATOES Add 85g/3oz butter and 150ml/5-6fl oz double cream to the mashed potato. Season to taste with salt and freshly ground black pepper. Add nutmeg to taste and mix until smooth and creamy.
Heavy cream will make for the creamiest mashed potatoes, but whole milk or half and half will also work. Don't use anything with less fat than whole milk, otherwise, your potatoes won't be as flavorful or creamy.
Potatoes cooked in the microwave are ready in a fraction of the time and still come out soft and fluffy and perfect for loading with toppings.
Step 1Wash potato thoroughly and pat completely dry. Pierce 3 to 4 times with a fork. Step 2Place potato on microwave-safe plate and microwave 7 minutes, turning over halfway through cooking. If your potato isn't fork-tender after 7 minutes, continue microwaving in 1 minute increments until fully cooked.
Soaking potatoes in water helps remove excess starch. Excess starch can inhibit the potatoes from cooking evenly as well as creating a gummy or sticky texture on the outside of your potatoes. Cold water is used because hot water would react with the starch activating it, making it harder to separate from the potatoes.
Turn the burner on high and bring water to boiling. Reduce the heat to medium-low or low. Cover the pot with a lid. Cook the potatoes in gently boiling water until tender, about 15 minutes for small Red Potatoes, New Potatoes or cubed large russet potatoes, and 20 to 25 minutes for quartered potatoes.
10 to 12 minutes for peeled and cubed potatoes. 15 to 20 minutes for whole red or Yukon gold potatoes. 25 to 30 minutes for whole russet potatoes. You'll know they're done when they pierce easily with a fork.
Cubed spuds will take around 15 minutes where larger chunks or whole new potatoes will be 20-25 minutes. To check when they are done, pierce the potatoes with the tip of a knife to see how much resistance there is. If it goes in easily, you're done!
When too much starch gets released, the potatoes become gummy, gluey, and unappetizing. Overworking the potatoes can happen in a couple ways: either by simply handling them too much, or by using a food processor, blender, or similar tool, which mixes the potatoes too aggressively.
