Melting Sweet Potatoes - The Original Recipe (2024)

FAQs

Why do you need to soak sweet potatoes before cooking? ›

TIPS & TRICKS to Make this Recipe: The main secrets to achieving that incredible crispy texture, is to soak the cut sweet potatoes in cold water for at least 30 minutes. This helps remove the starch from the sweet potatoes so they´re not limp & soggy.

The baking soda breaks down the potato's surface, creating a rough texture that enhances crispiness upon roasting. Then, before roasting, the par-boiled potatoes are tossed with olive oil, seasoning, and potato starch. The potato starch serves as a coating that crisps up beautifully as the potatoes roast.

Bake, don't boil

It intensifies their flavor and creates a richer taste compared to boiling, which can result in a watered-down, bland flavor. As the oven temperature rises (when baking), the molecular structure of the sugar molecules in the sweet potatoes begins to change.

How to tell if sweet potatoes have gone bad. If your sweet potato is soft in spots, smells rotten, or oozes a mysterious liquid, that potato should be discarded. Another sign that sweet potatoes have taken a turn for the worse is if they start growing stalky purplish sprouts.

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.

There is not much difference between boiling sweet potatoes with the skins on versus peeling them, but you will get a boost of fiber and potassium if you keep the skin on. The skin also adds a subtle texture to each bite. If you're looking for a smoother mash, peel the potatoes first before boiling.

The potatoes themselves get a rich, almost toffee-like complexity due to the slow roasting. Adding butter that's been cooked down until its milk solids just begin to turn brown and nutty accentuates that flavor even more. Some folks like to add cinnamon, nutmeg, or other spices to their sweet potatoes.

Playing With pH: Why You Should Add Baking Soda to Your Water. In my previous roast potato recipe, I recommended adding a splash of vinegar to the water for the initial boil. The idea is to control the breakdown of pectin, the cellular glue that holds vegetables together. Think of it as the mortar between bricks.

They're high in fiber and antioxidants, which protect your body from free radical damage and promote a healthy gut and brain. They're also incredibly rich in beta carotene, which is converted to vitamin A to support good vision and your immune system.

Boiling may actually retain most of the antioxidant power of sweet potatoes, compared to roasting and steaming. If we compare baking to boiling microscopically, boiling helps thin out the cell walls and gelatinize the starch, which may enhance the bioavailability of nutrients.

What are the disadvantages of sweet potatoes? ›

Sweet potatoes contain high amounts of oxalates that may increase the risk of calcium-oxalate kidney stones. Sweet potatoes contain beta-carotene, and their excessive consumption can lead to hypervitaminosis A (vitamin A toxicity), in which excess vitamin A accumulates in the liver.

But, microwaved sweet potatoes actually retain more of their nutrients as opposed to boiled sweet potatoes.

If you have diabetes, you can eat sweet potatoes daily — as long as you factor the vegetable's carbohydrate count into your meal planning. “Sweet potatoes are a source of carbohydrates, which raise blood sugars,” says White.

The Bottom Line

Sweet potatoes are full of antioxidants, vitamins and fiber to support your eye, digestive and heart health. They're generally safe to eat daily, especially if you eat them with calcium to prevent calcium oxalate kidney stones. There are so many fun and tasty ways to eat sweet potatoes.

Types of Potatoes to Soak

"Sweet potatoes can also be peeled and stored in water for up to 24 hours."

It's very important to wash potatoes before cooking with them because they're root vegetables. Since they grow underground, potatoes likely carry residual soil, bacteria, and pesticides when you buy them.

To remove excess starch, place cut sweet potatoes into cold water making sure the cut surfaces are submerged. This step is especially recommended for "kinton" (Japanese-style mashed sweet potato) and other lightly seasoned dishes where a delectable color is desired. Soaking time of about 5 minutes is sufficient.

But the new research by the UK team led by Dr Rachel Burch from Leatherhead Food International found that a simple measure of pre-soaking potatoes before frying can dramatically reduce the formation of acrylamide and may therefore reduce any subsequent risk it may pose.
