250 grams of potatoes

method of work

1. Prepare 250g of potatoes, and wash the surface soil with clear water.

2. Peel off the skin of the washed potatoes. If they are not used immediately, soak them in clear water to prevent the starch on the potato surface from turning red when it is oxidized by air.

3. Prepare a vegetable wiper that can wipe potatoes into a paste.

4. Stand the vegetable cleaner in a stainless steel basin and rub a potato back and forth on the vegetable cleaner.

5. Rub all potatoes into mashed potatoes for later use.

6. Add an appropriate amount of cold water to the rubbed potato paste, and grab the potato paste repeatedly by hand without touching the surface of the potato paste.

7. Remove the starch from the mashed potatoes to make the water turbid.

8. Drain the mashed potatoes with a colander, leaving muddy starch water in the basin.

9. Put the mashed potatoes in another pot, add a proper amount of cold water, and grab the mashed potatoes repeatedly by hand without touching the surface.

10. Take out the starch in the mashed potatoes to make the water turbid. Drain the mashed potatoes with a colander, leaving muddy starch water in the basin.

1 1. Repeat the washing for several times until all the starch in the mashed potatoes is washed out, and pour the washed starch water into a basin, which is starch powder slurry.

12. Put aside the starch slurry and let it stand for about 30 minutes.

13. Until the water in the basin becomes clear.

14. Pour out the water in the basin slowly, leaving thick starch slurry in the basin, and put the basin in direct sunlight to dry.

15. Dry in the air until the powder is dry, and knead the powder loosely by hand, which is the finished pure potato starch.
