2. Cook the beans. Rinse the soaked beans 1-2 times and cook on a medium heat for about 1 or 1 ½ hours. One hour into the cooking remove 3 beans from the pot and taste them. If all of them are soft - beans are ready; If you use canned beans, move on to the next step.

3. Mash the beans. Drain the mixture of cooked beans and reserve all cooking liquid. Using a potato masher, mash half of the drained beans. If you're using canned beans, drain them, reserve the liquid, transfer the beans into a large bowl and mash half of the beans.

4.Chop the walnuts. I like using food processor. Simply pulse the walnuts until they are a size of a buckwheat seed. If you don't have a food processor, you can chop the walnuts by hand or add them to a plastic bag, seal it and pound with a rollin pin.
