Why do you soak potatoes in water before roasting? ›

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.

I love it when cooking involves a bit of a science experiment. In this case, research suggested adding baking soda to the pot when parboiling potatoes; having water of higher alkalinity than usual helps the outside edges of the potatoes break down more, opening up the possibility of a crisper outside texture.

Roasted potatoes can become soggy if the water content in the potato isn't fully cooked. Different potatoes have different water content percentages. Also, be mindful of the oil. Potatoes can react like sponges; too much oil can make your potatoes appear to be soggy.

In most potato recipes, I recommend starting potatoes in cold water and bringing them up to a boil. This helps ensure that the exteriors don't turn to mush before the insides have a chance to cook through.

The potatoes cook on the inside when you parboil, so the baking time is basically crisping them up to perfection, which we do at a high oven temperature. If the potatoes are raw, when you use a high temperature, the outside of the potatoes will burn before the inside cooks.

Soak the potatoes in cold water to remove the excess starch from the outside of the potato. There are a few reasons why you want to remove that starch (it makes the potatoes burn, it keeps them from crisping up, it turns to sugar) but all you really need to remember is to soak them at least one hour.

The main reasons to cut the potatoes and pre-soak in water are: To allow the excess starches and sugars to be removed from the outer surface of the fry strips AND to keep the potatoes from browning prematurely from exposure to air. Covering in water helps the potato from turning a dark color.

Dunk the Potatoes in a Saltwater Solution

This step is extremely important because it seasons the skin and encourages it to dry and crisp in the oven.

The acid in the vinegar can also help to slightly break down the surface of the potatoes, aiding in the development of a crispier texture during frying. Additionally, the vinegar can contribute to a golden-brown color on the exterior of the fries.

The Vinegar Trick

In his recipe, López-Alt shares his secret for perfectly cooked potatoes every time: Adding vinegar to the water (specifically, 1 tablespoon of vinegar per 1 quart of water) prevents overcooking. This one tip has transformed potato salad for Kristina Razon, the Senior Food Editor at Kitchn.

Why do restaurants put salt on the outside of baked potatoes? ›

Why is it common to salt the exterior of a baked potato? A: Chefs started doing this years ago to allow the salt to absorb or draw out the moisture of the potato while baking, which results in a dry, fluffy potato. They used to do something similar with prime rib, sometimes baking it over rock salt.

'Though we all love a crispy roast potato, it can be really easy to mess them up,' said Jeff. 'If you drown them in too much oil, they'll burn on the outside and be undercooked on the inside. ' He recommends par-boiling your spuds then fluffing them up before roasting for best results.

A general rule of thumb is to parboil potatoes until they are fork-tender but not falling apart, this can range anywhere from 15 minutes for small potatoes to 25-30 minutes for large whole potatoes.

If roasted potatoes lack their crunchy sheen, overcrowding is usually the culprit. Just as overcrowding bacon or mushrooms in a saucepan causes disappointingly mushy results, placing potatoes too close to each other on a baking sheet will prevent them from crisping while they roast.

The RSVP International Hasselback Potato Guide is really the key to hassle-free Hasselback-ing. Once I wash my potato, I pierce it with the guide and use my knife and the guide's prongs to cut the potato, over and over again, going from right to left.

Parboil them in a pan of boiling salted water for 15 minutes – this will ensure that the insides become really fluffy. 2. Drain in a colander and leave to steam dry for 2 minutes – this will help the fat to stick to the potatoes.
