3. Wash the cut potato shreds several times with water, wash the starch on it thoroughly, and wash until the water is very clear, so that even if it is not blanched, it is still crisp and non-sticky. After washing, soak in clean water to prevent oxidation from turning black.
4. Wash and cut the green peppers into fine strips; cut the ginger into diamond-shaped slices, cut the shallots into sections, and then grab the appropriate amount of dried pepper segments and peppercorns for later.
5. After the ingredients are ready, we start cooking: burn the oil in the pot, pour out the hot oil after fully sliding the pan, and add the cool oil, this step is mainly to prevent sticking to the pan. When the oil temperature is 50% hot, pour in the onion ginger, dried chili pepper and peppercorns, and then pour in a little white vinegar, open a small heat to incense, this step is mainly to extract the sauce aroma, evaporate the sour taste.
