I will discuss tips and methods that you can use to make sure your potatoes come out delicious and not stringy.

Sweet Potatoes and Stringy

These potatoes are a nutritious and delicious addition to any meal. They are an excellent source of vitamins, minerals, and fiber.

However, when cooked improperly, they can become stringy. 

The stringiness results from the sugars in them breaking down. When cooked incorrectly, these sugars can form long strands that give the potato a stringy texture.

This can happen if the potato is overcooked or cooked in water that has been overboiled. Fortunately, you can take steps to prevent stringiness.

Tips for Keeping Sweet Potatoes from Being Stringy

Choose the Right Sweet Potato

The first step to preventing being stringy is to choose a suitable variety. Look for firm, small- to medium-sized potatoes with smooth, unblemished skin.

Avoid large potatoes and those that are soft or have discolored spots, as these can be stringy.

Also, if you want to avoid strings, choose a dry sweet potato.

  • Soft ones are higher in sugar and moisture, and they’re the kind that is more likely to be stringy.
  • Dry ones have less sugar and moisture, and they’re the kind that is less likely to be stringy. 

Cook the Sweet Potatoes Properly

Reduce the heat and simmer for 15-20 minutes or until tender. Alternatively, steam the potatoes in a steamer basket over boiling water for 10-15 minutes or until tender.

Don’t Overcook

Factors That Cause the Stringiness

Several factors can cause the potatoes to become stringy. These include overboiling the water, cooking the potatoes too long, and choosing a potato with high starch content.

  • Overboiling: Overboiling the water can cause the starches in the potato to break down, resulting in a stringy texture. That is because boiling water breaks down the starches more quickly, which can cause them to become stringy.
  • Cooking too long: They can become stringy if you cook them for too long. That is because the starches break down and form strings when exposed to heat for a prolonged period.
  • High starch content: These potatoes high in starch are more likely to become stringy when cooked. Starch breaks down more quickly when heat exposure results in a stringy texture.
  • Age of sweet potatoes: As the potatoes age, their starches break down more quickly when exposed to heat. Older potatoes are more likely to become stringy than younger potatoes.
