Combine everything together in a large bowl and whisk with a fork until well combined (If you're not using activated buckwheat kernels don't forget to soak your buckwheat for at least 2 hours and rinse before adding to the rest of the ingredients).
You can purchase already activated buckwheat kernels, but if you don't have access to them all you need to do is soak your 2 cups of buckwheat kernels in water for a minimum of 2 hours or for up to 8 hours. Once they have finished soaking, give them a really good rinse (they can get a little slimy, but that is perfectly normal!)
*IMPORTANT* If your porridge seems a little dry once it has set over night, you may need to add more milk (up to 1 cup), just stir through and let sit for 5 minutes before serving.
