In the bowl of an electric mixer, place 2 cups of Einkorn flour and the salt. Add yeast to flour mix.
Remove from heat and add sugar. Stir until well combined.
Add remaining flour and mix until well combined, switch to dough hook and mix on low for 5 minutes.
Allow to cool for about 30-60 minutes before slicing (or they will crumble).
If you find the that buns fall apart while being eaten, butter and toast the cut sides of the bun before serving.
Freeze for up to 1 year.
To Thaw: Remove from freezer and allow to thaw, in an open bag, on the counter. Or, if you're in a hurry, place rolls in a cold oven and set the temperature to 350°. Once the pre-heat is finished, remove the rolls and they should be ready to use.
