How can the cooking time of whole grain cereals be shortened?

To shorten the cooking time of whole grain cereals, you can soak them in water overnight, which helps to soften the grains and reduce cooking time. Alternatively, using a pressure cooker can significantly expedite the cooking process. Additionally, using finer grain varieties or grinding the grains into a flour can also lead to quicker cooking times. Finally, cooking the grains in boiling water rather than simmering can speed things up as well.
