Use sesame oil anytime. Just make sure you don’t overcook it. Let it sit on the stovetop for 5 minutes before serving. In order to get rid of any impurities while using the oil, you need to strain them off after cooking. There are various ways to strain the oil. One such way is to drain off the excess oil after removing the seeds and add water until the level reaches half full. Once cooled enough, remove the sesame seeds and discard them. Then heat up the sesame oil once again and allow it to cool completely before storing in a glass jar. Storing your extra oil is advisable to prevent spoilage.
