If you use a microwave oven for cooking, you can simply reheat the swollen buckwheat in m / w in a suitable container, covering it with a lid.
I use a frying pan with a non-stick coating and a thick bottom for cooking buckwheat porridge. A coated saucepan is also perfect for these purposes.
So, for cooking – buckwheat porridge with milk, heat up the pan and spread the buckwheat groats. Stirring the buckwheat with a spatula, evaporate the excess liquid. It will only take a couple of minutes. In this version, I do not salt buckwheat. But it’s a matter of taste.
If you want to cook buckwheat as a side dish to meat, etc. or serve it hot, then first heat up a little oil in a frying pan, it will taste better with butter, but vegetable oil is also perfect for fasting, then, as in the first version, put the buckwheat and warm it, stirring, over medium heat. Don’t forget to add salt.
