We will discuss here the reasons of blanching potatoes.

1. To Remove Excess Starch

Potatoes contain a large amount of starch, which can cause them to become mushy and disintegrate when cooked.

Blanching potatoes helps to remove some of the excess starch and prevent them from becoming too soft.

This results in firmer and more appealing potatoes, which are better suited for dishes that require them to hold their shape.

2. To Remove Skins

Blanching potatoes can make it easier to remove their skins, especially if you are using new potatoes, which have a thin and delicate skin.

By briefly boiling the potatoes and then immersing them in cold water, the skins will loosen, making them easier to peel.

3. To Enhance Flavor and Color

Blanching potatoes also helps to enhance their flavor and color. The brief exposure to heat and water helps to bring out the natural sweetness and brighten the color of the potatoes.

This, in turn, makes them more visually appealing and enhances the overall taste of your dish.

4. To Preserve Nutrients

Blanching can also help to preserve the nutrients in potatoes. By briefly cooking the potatoes, you reduce the amount of time they spend in the oven or on the stove, which can cause some of the vitamins and minerals to be lost.

5. To Kill Bacteria and Germs

Blanching can also help to kill any bacteria or germs on the surface of the potatoes, making them safer to eat. This is particularly important if you are using potatoes in a dish that will not be cooked again, such as potato salad.

Here are steps of blanch potatoes correctly:

Step 1: Choose the Right Potatoes

When blanching potatoes, it’s essential to choose the right type of potatoes.

Waxy potatoes, such as new potatoes, are the best for blanching as they hold their shape better than starchy potatoes, such as russet potatoes.

Step 2: Cut the Potatoes

If you are blanching whole potatoes, make sure to cut them into evenly sized pieces so that they cook evenly. If you are blanching sliced or diced potatoes, make sure they are cut to the same size.

Step 3: Boil the Water

Fill a large pot with water and bring it to a boil. The water should be well-salted to enhance the flavor of the potatoes.

Step 4: Add the Potatoes

Carefully add the potatoes to the boiling water and cook for 2-3 minutes or until they are slightly tender but not fully cooked.

Step 5: Transfer to Ice Water

Once the potatoes have been blanched, immediately transfer them to a bowl of ice water. This will stop the cooking process and help to set their texture and color. Let the potatoes cool in the ice water for 2-3 minutes.

Step 6: Drain and Use

After cooling, drain the potatoes and pat them dry with paper towels. They are now ready to be used in your desired dish.
