Step 1

Combine the starter, water, rye flour and 1 cup of the bread flour. Mix with the paddle on low speed until it forms a thick batter. Cover the bowl and set aside for 30-60 minutes.

Step 2

If using a stand mixer, change to the dough hook. Add the malt syrup, salt and the rest of the bread flour and mix until the dough begins to clean the bottom of the bowl and form a ball around the hook. If the dough is still extremely sticky and does not clear the sides of the bowl, you can add up to ¼ cup more flour, a tablespoon at a time. If mixing by hand add as much of the bread flour as you can then turn the dough out onto a floured surface and finish kneading in the rest of the flour.

Step 3

Knead for 3-4 minutes on medium speed or 4-5 minutes by hand. Turn the dough out onto a lightly floured surface and knead into a smooth ball. Place the dough in a lightly oiled bowl, turn once to coat the dough. Cover the bowl and set it aside at room temperature.

Step 4

After 30 minutes uncover the bowl, lift one side of the dough and fold it into the middle of the dough. Repeat with the other three sides of the dough then flip the dough over. You're basically turning the dough inside-out to redistribute the yeast. Cover the bowl and after 30 minutes repeat the procedure. Cover the bowl and after 60 minutes repeat the procedure again.

Step 5

Cover the bowl and after 60 minutes knead the dough, return it to the bowl. By now the dough should be lively, elastic and airy. If the dough is still sluggish give it another hour or two at room temperature. Cover tightly and refrigerate over night.

Step 6

Remove from refrigerator and dump the cold dough onto floured surface. Sprinkle the dough with 1 tablespoon caraway seeds and knead to distribute the seeds

Step 7

If you want two smaller loaves, divide the dough in half. Knead the dough into a smooth ball then taper two ends to form an oblong football shape. If baking in a Dutch oven form the dough into a round ball.

Step 8

Place on a wooden peel or sheet pan sprinkled liberally with corn meal. If you want to bake the bread in a Dutch oven place the dough onto a sheet of parchment paper. Cover with a damp kitchen towel and leave in a warm place until doubled in size and it springs back slowly when poked, about 1 ½ hours.

Step 9

Meanwhile, preheat the oven to 425 °F. If you have a baking stone preheat that in the oven. If you want to bake the bread in a Dutch oven or other heavy pot put that in the oven to preheat.

Step 10

Make 5 diagonal slashes in the dough with a single edge razor or very sharp knife. Brush dough with egg white and sprinkle with the other tablespoon of caraway seeds.

Step 11

Slide the dough onto the preheated stone or slide the sheet pan into the oven. The bread is ready when the internal temperature is 200 °F. Baking time is about 35 minutes.

Step 12

If using the Dutch oven to bake follow these directions: Remove the preheated pan from the oven and remove the lid. Use the parchment paper to lift the loaf into the Dutch oven. Replace the lid on the pot and slide it into the oven. Bake for 20 minutes. Remove the lid from the Dutch oven. The loaf should be well risen and pale in color. Continue baking another 20 minutes until the loaf is nicely browned and beginning to crisp. Remove the pan from the oven. Use the parchment to lift the loaf out of the pan. Use the parchment to place the loaf directly onto the rack in the oven. Bake another 5-10 minutes until the loaf is deeply browned and very crisp. Total baking time is about 40-50 minutes.

Step 13

Cool completely on a wire rack before slicing.
