Next, stir-fry the seasoning, peel the garlic and cut it into powder for later use. Add the right amount of oil to the pot and heat it to 40%. Pour the minced garlic into the pot and stir-fry until fragrant. Then pour the prepared seasoning into the pot and stir-fry it slowly over low heat until thick.
