Dissolve the yeast and honey in warm water and let stand for 5–10 minutes until foamy.
Mix the einkorn flour and salt in a large bowl.
Add the yeast mixture, olive oil, and apple cider vinegar. Stir until a soft dough forms.
Knead gently for 4–5 minutes until smooth. Avoid over-kneading.
Place the dough in a lightly oiled bowl, cover, and let rise for about 1 hour or until slightly doubled.
Gently punch down the dough and shape it into an einkorn sandwich loaf. Place it seam-side down in a greased 9×5-inch loaf pan.
Cover and let the dough rise for 45–60 minutes until puffy.
Bake at 375°F (190°C) for 33–37 minutes, or until the loaf reaches an internal temperature of 190°F (88°C).
Cool in the pan for 10 minutes, then transfer to a wire rack to cool completely before slicing.
