Add enough oil into pot or work being used for frying so that it is at least 1 inch deep. Heat oil to medium-high heat. Once the oil is hot, carefully drop in a few chips. Within a few seconds they should heat up and expand. As soon as they open up and expand, immediately remove them from the oil, otherwise they will start to burn and lose their color. Repeat until you finish your box or reach desired amount you want to make.
