Many people like to eat vermicelli when cooking. Vermicelli is the first choice when making stews or hot pot. Generally speaking, there are more sweet potato vermicelli, and the vermicelli made with sweet potato is stronger and has a great taste. But many people don’t know how to tell the difference when they buy it, so sometimes they choose unhealthy vermicelli. So how should they tell the difference?

1. Crisp - because the raw material is only sweet potato starch, which is dried in the sun. It is very brittle after drying and can be broken by just grabbing it with your hands, and it does not easily return to moisture after being dried in the sun. The purported pure sweet potato flour sold in the market will not break when exposed to the sun for 10 days. When buying sweet potato vermicelli, be aware that if it breaks into pieces as soon as you catch it, it must not be made from sweet potatoes.

2. Color. Pure sweet potato vermicelli will have various colors because the quality of the sweet potato starch used is different, and some will be darker. The ones treated with starch will be whiter, but the color of sweet potato vermicelli is generally darker, while sweet potatoes are translucent, especially after cooking, they become brighter and more chewy. A lot of experience tells me that vermicelli made from pure sweet potato is yellowish and green. Vermicelli of this color are all real, and there is also a very white and transparent kind that is also sweet potato vermicelli.

3. Pure sweet potato vermicelli is very resistant to cooking, and there is another big difference from fake vermicelli: the more pure sweet potato vermicelli is soaked, the more it becomes. This means that when you first soak it, it will be half a bowl. If you soak it for a few hours, it will become larger. This is vermicelli made from sweet potatoes. You can use this method to distinguish it.

4. Taste. Pure sweet potato vermicelli has a sweet potato taste when you chew it dry. Of course, the fake ones don’t have it. If they do, they smell like rotten plastic. After cooking, the texture is smooth and chewy. This is what we call chewy vermicelli, made from sweet potatoes.
