In a large bowl, combine yeast, sugar and warm water. Let stand for 10 minutes or until bubbly.
Combine flours and salt by hand then stir until it all begins to come together. Turn dough out onto a floured counter, flour your hands then knead until you have a smooth dough (only about 2 minutes). Let dough rest for 10 minutes. The dough will become stickier while it rests because it’s absorbing the liquid. NOTE: We strongly recommend you weigh your einkorn flour, if possible, for better accuracy. If you don’t have a scale, fluff the flour with a fork before you measure it in a cup.
After the dough has rested, knead for another minute or two. Don’t be tempted to over flour the dough at this point. It should remain sticky.
Form dough into a ball, then place in a large oven-proof glass bowl heavily coated with butter. Add 4 tsp of olive oil to the bottom of the bowl then toss to coat both sides in oil. Cover with a clean towel and let rise (about 40 minutes). It does not need to double in size like traditional dough.
Preheat oven to 375 degrees. When the oven is hot, place the bowl in the oven and bake for 35 minutes. The bread will sound hollow when tapped and be at an internal temperature of 200 degrees. Invert the bread onto a rack and let it cool.
Slice and use for your favorite sandwich.
Notes
Remember—einkorn flour dough isn’t meant to be overworked. It should be a bit sticky!
