Grind 1 1/3 cups of wheat berries in a grain mill on the finest setting.
In a large bowl, add the flour, salt, and baking powder. Mix well.
Drizzle the olive oil over the flour mixture and mix until coarse crumbs form.
Heat the water to a simmer and pour over the flour mixture.
Mix well.
Turn onto a floured surface and knead for a couple of minutes until the dough ball is smooth and cohesive.
Return the dough to the bowl and cover with plastic wrap or a tea towel.
Let the dough rest at room temperature for 30 minutes.
Turn the dough onto a lightly floured work surface and divide into 12 equal pieces.
Roll each piece of dough into an 8-10 inch circle with a rolling pin. Roll out as thin as possible.
Preheat a skillet over medium to medium high heat.
Add a little oil to the pan and place a tortilla in the pan.
Let cook for 30-40 seconds and then flip and continue to cook 30-40 seconds for a total of 1-2 minutes cooking time.
Place each cooked tortilla on a plate and quickly cover with a towel to hold the steam in.
