Combine the yeast, sugar, melted butter, egg, and milk in the bowl of an electric mixer fitted with a dough hook. Beat on low speed for 1 minute.

Add the salt, rye flour and all-purpose flour. Beat at low speed until all of the flour is incorporated, about 1 minute.

Then, beat at medium speed until the mixture forms a ball, leaves the sides of the bowl and climbs up the dough hook.

Remove the dough from the bowl.

Using your hands, knead for a couple of more minutes.

Roll into a large ball.

Roll the dough in the oil and turn it to oil all sides.

Place into a lightly bowl.

Cover with plastic wrap and set aside in a warm, draft-free place until it doubles in size, about 1 hour.

Take the dough out of the bowl, knead it again for 5 – 10 minutes and place back in the bowl and cover for another hour.

Preheat the oven to 350 degrees F and spray a baking sheet.

Cook for 45 - 50 minutes.

Serve and enjoy!
