The term 'Pour Through a Sieve' can be summarized as the process of straining, which is a 6-letter word. Straining is a process that involves passing a liquid or other substance through a filter or sieve in order to separate out any impurities or solid particles. This process is often used in cooking to remove lumps from sauces or soups, or to separate out the seeds from fruit juice. It can also be used to purify water or other liquids.
