Simple boiled method: Use ½ cup grains (either oats alone or mixed with other grains) to 2 cups water.
Bring the water, plus a dash of salt, to a boil in a pot.
Slowly add the grains and the nuts or fruit (if using), stirring to prevent clumping. Reduce the heat to a low simmer and stir occasionally for about 10 minutes (or less for an al dente texture). Most, but not all, of the water should be absorbed.
Place an absorbent kitchen towel or several paper towels on top of the pot and close the lid over the towel. This will absorb additional moisture and allow the grain to reach full plumpness.
Let the grains rest for 10 to 15 minutes and serve warm with any of the toppings suggested above. If a richer taste is preferred, add the suggested optional ingredients before serving.
Toasted method: Heat 1 T. coconut oil or butter over a medium flame.
Add the grains, the seeds (if using) and the nuts (if using), lower the heat and toast while stirring frequently until the mix is lightly browned and fragrant—about 5 to 8 minutes.
Add toasted grains to the water and dried fruit and continue to cook using the simple boiled method, above.
