Why do people put vinegar in mashed potatoes? ›

The addition of a mildly acidic vinegar to a starchy veggie like potatoes not only deepens the flavor profile, but it also helps to tenderize the tubers.

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.

Soak the potatoes in water for at least 4 hours, up to overnight. This step is crucial to really get all of the excess starch off. Fill a large pot with water, rinse off the potatoes one last time and add them to the cold water. Salt the water, place the pot on the stove and turn on the heat.

Vinegar causes potatoes to develop a thin crust on their exterior layer, which is what is required to preserve them from becoming mushy or disintegrating.

This is why you should be adding a splash of vinegar to the water each and every time you boil potatoes. A little will go a long way, so just a tablespoon will do for every four cups of water. Keep the ratio going and double the vinegar for eight cups, and so on.

When exposed to light, potatoes manufacture increasing amounts of chlorophyll as well as two bitter- tasting alkaloid compounds , solanine and chacocine. In high concentrations, these can not only make potatoes taste bitter but also can cause headache and stomachaches.

Just like you might use a squirt of lime juice to keep guacamole from browning, a bit of lemon juice or white vinegar in the bowl with the potatoes will ward off gray hues. Use one teaspoon to a half gallon of water to get all the anti-browning impact with no noticeable flavor changes.

Place potatoes into a pot and add 1 1/2 cups vinegar with 3 cups cold water (or enough to just about cover the potatoes). Add in 1 tbsp salt, give it a stir then bring to a boil. Cook until knife tender, around 25mins depending on the size of potato chunks.

They just taste rich (almost impossibly so). They do, however, feel creamy, because egg yolks are also emulsifiers (and are, in fact, the ingredient in mayo that makes it an emulsifier). The yolk emulsifies water and fat to create a cohesive, velvety bite, while providing a little fat and body of its own.

You can use what you have on hand: Flour, cornstarch, or powdered milk are all solid options that are probably already in your pantry. Potato flour and potato starch would work as well. Stir in the thickening agent gradually, about a tablespoon at a time, until the potatoes have reached your desired consistency.

Should I melt butter before adding to mashed potatoes? ›

A word about butter: Don't melt butter before stirring it into the potatoes because the milk solids and fat will separate. You can add cold butter to your hot potatoes since the butter will melt as a whole and distribute the fat and milk solids evenly.

Drop a whole russet into the pot and by the time the outside has cooked through, the inside will still be raw. Larger potatoes should be cubed to ensure they cook evenly (peeled first if desired). Smaller potatoes tend to have thin skins and can be boiled whole, no peeling required.

The secret ingredient is just ice-cold water.

You soak the potatoes in iced water before they are cooked. This eliminates much of the starches in the potatoes, resulting in a super light and fluffy mash.

Vinegar helps boiled potatoes hold their shape

Since the objective is to fully cook the potatoes (without making them mushy), it's important to note that you just need a bit of vinegar to get the job done. Adding too much vinegar could cause the potatoes to cook way slower than desired, so it's all about balance.

So when vinegars free hydrogen ions interact with starches, the former alter the latter's molecular structure and changing their texture and consistency.

Any vinegar will do

This crust is what's necessary to help them keep their shape and not become mushy or fall apart when boiling. The home cooks over at Reddit say this is because vinegar's acid prevents the pectin in potatoes from breaking down too quickly.

The acidity or sourness of vinegar brightens the flavor of food and adds balance to a rich dish. It is found in popular kitchen staples like salad dressings, marinades, sauces, mayonnaise, and ketchup. Vinegar can change the texture of foods.
