Ah yes, good old buckwheat. Let me quickly tell you what this food represents for me and why it's important to know how to cook buckwheat with love. Stay with me :).....
Rinse the buckwheat in cold water a few times not through a colander but rather get your hands in there and swirl it around to rinse properly.
Now you can put it in a colander/strainer and leave to drain
Heat a skillet and transfer the drained the buckwheat into the pan to roast. Roast the buckwheat seeds (roast not burn)
Boil water in a kettle, add the hot water into a microwave dish, add in the buckwheat, microwave on high speed for 5 minutes. Don't take it out of the dish immediately, let it sit lid on for 5 minutes.
Drain any excess water through a strainer fluffing with a fork
Remove the lid and fluff. Add salt, chili and drizzle olive oil.
Notes
I see not reason to soak buckwheat because it cooks in a few minutes anyway. You can cook buckwheat exactly as you would cook rice so you can use the microwave or the stove in the same way too. If using the stove, same procedure, either bring the water to a boil or boil a kettle of waterUsing hot water as opposed to cold water after roasting it simply helps the buckwheat to steam in the hot water.
