If you are not sure whether the cooking is good or not, you can pinch it with chopsticks and then pinch it a little hard. Then wash a handful of onion and garlic, cut the onion into chopped green onion, cut the garlic into powder and cut the millet into small pieces; Clean the water in the pot, boil it, add the cooking oil that doesn't reach the bottom of the pot, heat it, and then change it to medium heat. Pour chopped green onion, garlic powder and millet spicy into the pot and fry in onion oil for about three minutes. Add a proper amount of salt, soy sauce and vinegar to the cooked fern root powder, and finally pour in the fried onion oil, stir it and cool it a little. Fern root powder can be eaten after fully absorbing the sauce.
