2. Scientific method for judging potato doneness
According to the latest research from the School of Food Science and Technology of China Agricultural University, potatoes will go through three stages during the cooking process:
| stage | temperature range | starch state | Taste characteristics |
|---|---|---|---|
| medium rare | 60-70℃ | Partially gelatinized | Soft on the outside and hard on the inside |
| Suitable for ripeness | 85-95℃ | Completely gelatinized | Even and soft |
| overripe | ＞100℃ | Start decomposing | loose and brittle |
3. 5 practical judgment methods
1.Chopstick test: Use chopsticks to insert into the center of the potato. If it can penetrate easily without any resistance, it is considered cooked. According to the actual measurement video of cooking master Wang Gang, the accuracy of this method is 98%.
2.time comparison method: Reference for the time required for different cooking methods:
| cooking method | Cut into pieces (minutes) | whole (minutes) |
|---|---|---|
| Boiled | 8-10 | 20-25 |
| Steam | 12-15 | 30-35 |
| microwave | 5-8 | 12-15 |
3.visual observation method: The skin of ripe potatoes will appear slightly cracked and the edges will become rounded. Food blogger "Eclipse Diary" pointed out in a recent video that this method is suitable for judging the doneness of baked potatoes.

| variety | Best doneness performance | Common uses |
|---|---|---|
| Dutch potatoes | The epidermis is slightly wrinkled | Stew, curry |
| purple sweet potato | Uniform color on cut surface | salads, bakes |
| red potatoes | The epidermis is easy to peel off | Fried, pureed |
5. Analysis of common misunderstandings
1.Color changes may not be accurate: A recent Zhihu hot post pointed out that the color of some varieties does not change significantly after being cooked and cannot be judged based on this alone.
2.Significant impact of size: Potatoes with a diameter of 5cm need to be cooked 40% longer than potatoes with a diameter of 3cm. This is a key point that many novices tend to overlook.
3.Differences between old and new potatoes: New potatoes have more water and cook faster; old potatoes have a higher starch content and take longer. The "Potato Storage Guide" recently released by the Ministry of Agriculture and Rural Affairs explains this in detail.
Conclusion
Mastering the skill of judging the doneness of potatoes can not only improve the success rate of cooking, but also ensure the full release of nutrients. It is recommended to combine multiple methods for comprehensive judgment and pay attention to the specificity of different varieties. With the popularization of smart kitchen equipment, more accurate doneness detection technology may appear in the future, but the practical value of traditional methods is still irreplaceable.
