In a small pot, add the einkorn and toast over medium heat until fragrant. Let cool and transfer to a food processor or blender. Pulse until the einkorn in cracked into big pieces, usually 5 to 6, 1 second pulses.

Return the cracked einkorn to the pot and add the milk, water, salt, and maple syrup. Bring to a simmer, cover, and cook over low heat until the einkorn is tender and the porridge is thick, 35 to 45 minutes. Add more water/milk as needed to keep a good porridge consistency. Add the mashed sweet potatoes and stir until combined and heat.

Place in a bowl and top with your favorite toppings: pecans, cream, maple syrup, and/or cinnamon.
