How to choose delicious, sticky purple sweet potatoes
- You should choose sweet potatoes that are round or elongated in shape, without waists and not scratched on the body. When you squeeze gently, it should feel neither too hard nor too soft.
- In addition, you should also choose medium-sized sweet potatoes, not too large because large sweet potatoes often have a lot of fibers and are not tasty.
- Avoid choosing sweet potatoes with indentations on the body, with dark spots, pockmarked, or blackened because these are potatoes that have been stored for too long, spoiled, and cannot be processed anymore.
