To Know How to Grind Coffee Beans Without a Grinder? Grinding coffee beans without a grinder is easy with a few household tools. One of the best methods is using a mortar and pestle, which gives you control over grind size. You can also place the beans in a Ziplock bag and crush them using a rolling pin or heavy pan for a more even texture. A blender or food processor on pulse mode can work for coarser grinds, but be careful not to overheat the beans.
