What makes potatoes crispy science? ›

Crispiness is almost entirely due to the starch in potatoes, says Joseph Provost, a chemistry and biochemistry professor at the University of San Diego who co-wrote “The Science of Cooking: Understanding the Biology and Chemistry Behind Food and Cooking.” The two main molecules of that starch, a type of carbohydrate, ...

Add a coating

The starch will create a crispy coating on the outside of your potatoes.

Red potatoes are great for roasting, cooking in soups, or boiling or steaming for potato salad. The waxy nature of the flesh means they'll maintain their shape, but it also means they will get gluey when overworked, so you'll want to choose a different potato for mashing.

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.

Do I need to boil my potatoes first? Trust us: You seriously don't need to boil these spuds (or pre-cook them at all) before pan-frying. Slicing them thin allows them to cook through in the same amount of time that they need to get brown and crispy on the outside.

Cornstarch typically makes for a crispier finish than flour. Cornstarch absorbs moisture from the food and expands, giving deep-fried foods a crispy coating. When the food is fried, the moisture cooks out of the cornstarch, leaving a crackly, puffy coating on the outside.

After closely inspecting the brand of frozen French fries I often buy, I realized that they are coated in a blend of starches to help crisp them up. 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!

It makes the water alkaline which helps break down the surface of the potato and helps make your potatoes crispy!

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.

The Healthiest Potato is the Red Potato

After taking into account the mineral density, the vitamin density, the macronutrient balance, the sugar-to-fiber ratio, the sodium-to-potassium ratio, and the phytochemical profile, red potatoes are the healthiest potato with data from the USDA Food Database.

When should you not use russet potatoes? ›

When to avoid: Because of their high starch content, starchy potatoes don't hold together very well when cooked so avoid using them in dishes that require boiling, roasting or slicing like casseroles, potato bakes, gratins or potato salads.

The potato does not produce electricity; instead, it acts as an electrolyte or a buffer. Hence it forces the electrons to travel through the potato by separating zinc and copper and forms a complete circuit. By using only two potatoes, a small amount of potato energy or electrical energy is generated.

The hot oil ensures moisture can evaporate quickly from the outside of the fry. This is what makes your fries crisp up. Drying the outside also helps to accelerate the Maillard reaction. The Maillard reaction is a complex series of reactions between proteins and sugars and is what causes the potato to turn brown.

When cooked at high temperatures, sugars react with amino acids, including asparagine, in a chemical process known as the Maillard reaction. The reaction is what gives fried potatoes their prized flavor and color, but it is also what produces acrylamide.

If the salt concentration in the cup is higher than inside the potato cells, water moves out of the potato into the cup. This leads to shrinkage of the potato cells, which explains why the potato strips get smaller in length and diameter.
