Buckwheat flour should be all buckwheat flour, white and gray. Adding 20-30% wheat flour can increase ductility and elasticity. If it is not enough, you can add more, but not more than 50%. You can make noodles, noodles, arugula and pancakes.

Did you buy buckwheat flour? Look at the ingredients carefully. Maybe wheat flour was added.

More money is enough. It is best not to use additives. You can add a little tapioca starch to increase gluten and make the color more shiny.
