For the best result, you want to choose a starchy potato like Russets that will get a crunchy, crispy outside and fluffy, creamy inside when roasted. Other potatoes like Yukon Gold or red potatoes tend to have a softer skin when cooked, which might not crisp up the way you intend.

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.

Boiling your potatoes for a little bit before roasting helps make sure that you get that beautiful crisp crust on the outside. If you don't parboil your spuds, the outside skin will remain quite tough, meaning that whatever fat you use will not be able to get inside the cracks.

03/5Why vinegar is added to boiling potatoes? This hack has been suggested by several home cooks and chefs and the reason behind it is that vinegar can help the potatoes retain their shape. Vinegar causes the potatoes to form a thin crust that further helps in retaining their shape.

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.

In a video online, Gordon explained: “For crispy roast potatoes, you can depend on them, my tip is to parboil them, leave them to steam dry, then sprinkle them with semolina or flour, and then give them a good roughing up.”

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.

It's all about starch

Soaking potatoes in water helps to remove starch, a glucose molecule, from the tubers. Starches are sugars that can create a gummy or sticky effect on your spuds when cooked ― they're also why your hands feel so gritty after you've peeled potatoes.

Yes! 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.

What does cornstarch do for potatoes? ›

So, I decided to give the method a shot with roasted potatoes. And it turns out, coating the potatoes with cornstarch is the secret to super crispy roasted potatoes!

Baking soda will cause the potatoes to break down, making them a little mushy and fall apart. Vinegar will make them hold their shape better. Baking soda is good if you're making Kenji's crispy roast potatoes because the mushy potatoes will make a coating of fat and starch which helps them get crispy in the oven.

America's Test Kitchen often recommends adding baking soda to the water in which you will boil potatoes, which further coaxes out the starch molecules. Aim for ½ teaspoon baking soda for every 8 to 10 cups or water, or 2 to 3 pounds of potatoes.

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.

Potato juice is a highly alkaline drinks and acts similarly to antacids by neutralizing the acidity of the stomach. It has a calming effect on inflammation in the digestive system, and can be used to relieve heartburn related to gastritis or stomach ulcers.
