Start by rinsing the amaranth and quinoa under cold water using a fine mesh sieve. Drain well.
Add amaranth, quinoa, coconut milk and cinnamon to a saucepan.
Bring to a gentle boil, then reduce heat to low. Simmer for 15-20 minutes, stirring occasionally, until both grains are tender and the mixture thickens.
Remove from heat, cover, and let rest 5 minutes to allow extra absorption.
Stir in mashed banana. Mix until well combined and creamy.
Fluff using a fork, spoon into bowls, and garnish with banana slices, maple syrup, or your favorite toppings.
Notes
It is important to completely rinse your amaranth and quinoa, as this helps remove dust, bitterness, and natural compounds like saponins that can affect the taste. Rinse under cold water until it runs clear before cooking.
Use more or less coconut milk, depending on how thick you like your porridge.
