Recipe: Perfectly Creamy Mustard Mashed Potatoes (2024)

FAQs

Why add baking soda to mashed potatoes? ›

Just a pinch of baking soda is all you need to create mashed potatoes as soft as clouds. When you add baking soda, it reacts with the heat of the dish and the acid in the milk or cream to create small air pockets throughout the mash. These air bubbles translate to light and airy bites. Yum!

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.

It may seem like an unnecessary step, but there's a reason most recipes suggest you add hot dairy, not cold, to the taters. Throwing in a cold stick of butter and a splash of milk straight from the refrigerator will immediately cool down some of the spuds, which will prevent a creamy, smooth mash.

Instead of regular milk, pro chefs generally use a generous helping of buttermilk and plenty of half-and-half or (even better) heavy cream in their potatoes. If you think the bartenders up front are pouring heavy, they've got nothing on the cooks in the back who are in charge of the mashed potatoes.

The secret weapon, a good potato ricer (affiliate). This pushes the potatoes into strings, which helps them soak up every bit of the cream and achieve maximum fluffliness.

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.

Vinegar allows you to boil the potatoes the longest and keep them firm but I didn't get the soft outer surface I wanted. (I did get very creamy middles though!) Good, but not quite. Baking soda starts softening the outside right away, long before the middles are cooked.

Sour cream adds a little bit of tangy flavor and a boost of richness to mashed potatoes. It's a fun change from the standard milk or cream and butter combo usually flavoring mashed taters. You can even try your hand at making homemade sour cream from heavy cream!

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. It's also like when you make rice. The key to fluffy rice is to rinse off as much starch as possible.

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.

Does soaking potatoes in cold water make better mashed potatoes? ›

Yes, soaking cooked potatoes in cold water can help to freshen up their texture and taste as if they were just boiled. Here's how to do it: Place the cooked potatoes in a large bowl and cover them with cold water. Let the potatoes soak in the cold water for 10-15 minutes.

Thick-skinned varieties like russets will give you the fluffiest results. Steer clear of waxy red-skinned potatoes, which turn gluey when mashed. If it's too late to make the swap, change course and roast the potatoes tossed with oil, garlic and some fresh rosemary if you have it, instead of boiling them.

Using the wrong type of potato.

Because these varieties have a low starch content, they don't break down or absorb dairy as well as other starchier varieties, and often result in a gluey or gummy texture when mashed. Follow this tip: For fluffy mashed potatoes, use starchy potatoes, like Russets or Yukon Golds.

The best potatoes for mashed potatoes are a starchy varieties like russet, Idaho or Yukon gold. Starchy potatoes are best for mashed potatoes because they have a fluffy, almost airy texture that breaks down easily.

Adding egg yolks to a pot of mashed potatoes is an easy, dairy-free texture and taste upgrade that doesn't require any special techniques. The yolks harbor all the flavorful fats and emulsifying components and will thus effectively unify the fat and water in potatoes, translating to a smoother, uniformly creamy pot.

gold standard for a mash with a creamy, rich texture. Their medium starch content, density, and inherently buttery flavor make Yukon Golds great for all your mashing needs.
