Instructions
- Procedures:
- Mixing (by hand. See Note below for mixing with a stand mixer.)
- In a large bowl, sprinkle the yeast over the warm water to soften; stir to dissolve. (If using instant yeast, mix it with the flour, don’t dissolve it. Add the water to the rye sour and mix.) Add the rye sour, altus (if desired), pumpernickel color, pumpernickel flour, 2 ½ cups of common flour, and salt. Mix thoroughly until the dough pulls away from the sides of the bowl.
- Turn out the dough onto a floured work surface and knead, adding small amounts of flour as needed. Make the dough a bit stiffer than normal, since this dough softens as it is kneaded. Knead the dough until it feels smooth and silky (5-8 minutes).
- Note: I mix in a KitchenAid mixer. I put all the ingredients in the bowl and, using the paddle, mix well at Speed 1. Scrape the dough off the paddle and replace it with the dough hook. Knead at Speed 2 for about 8-10 minutes. If you do not use altus, the dough should form a ball on the hook and clean the sides of the bowl. With altus, even when an additional 50 gms of flour is added, the dough does not clean the bowl. I then hand knead until the dough is smooth and silky.
- Fermenting
- Shape the dough into a ball, place in a large oiled bowl, and turn to coat. Cover and let rise until doubled in size.
- Shaping & Proofing
- Punch out all the air, cut in half and shape into rounds, and let rest for 10 minutes.
- Shape into round loaves, long loaves or pan loaves. If baking free form, place the two loaves on a baking sheet sprinkled with coarse cornmeal. (Or on parchment paper if baking on a stone, which I prefer.) Cover and proof until doubled in size. (About 90 minutes, or more depending on room temperature). Brush with cornstarch solution. Score the loaves across if long dock them if round. If using caraway, sprinkle seeds on the top of the loaves.
- Baking
- Bake with steam in a preheated 375F oven until tapping the bottom of the loaf produces a hollow sound (30-45 minutes). The internal temperature should be at least 190F. If the crust seems soft, bake 5-10 minutes more. (The crust should be very firm when you take the loaves out of the oven. It will soften as the bread cools.)
- Note: I use a pizza stone for baking free form loaves. I heat it at least 1 hour before baking. I produce steam by preheating a cast iron skillet filled with lava rocks in the oven along with the stone and, right after putting my loaves in, pouring 1 cup of boiling water into the skillet. Be careful you don’t scald yourself with the steam!
- Cooling
- After baking, place on a rack to cool and brush again with the cornstarch solution. Let cool thoroughly before slicing and eating.
- This type of pumpernickel is one of the breads we always had in the house when I was a child. I usually ate it un-toasted, spread with cream cheese. My grandmother ate it spread with sour cream. I think this pumpernickel is especially good with smoked fish or herring, and it is my favorite bread to eat with scrambled eggs.

- NOTES:
- Notes on ingredients:
- Rye sour: This is a rye sourdough starter. You can make it from scratch. You also can easily convert a wheat flour sourdough starter to a rye sour by feeding a small amount of your existing starter with rye flour and refreshing it a couple of times.
- Altus: This is “old” rye bread cut into small pieces, soaked in water until saturated and wrung out. It was originally a way for bakers to re-use bread they hadn’t sold. “Waste not. Want not.” However, it does make for a more tender and flavorful bread and has become traditional. It is optional. I keep hunks of leftover rye bread in a plastic bag in my freezer to use as altus.
- Pumpernickel color: This is really optional but is necessary to give the “black” color expected of pumpernickel. It also gives the bread a subtle bitter undertone without which it just doesn’t taste “right.” You can use 1 tablespoon of powdered caramel color, instant espresso coffee or cocoa powder. I use powdered caramel coloring from King Arthur’s Baker’s Catalogue.
- Pumpernickel flour: This is whole grain, coarsely ground rye flour. You can use dark rye flour, but it won’t be quite the same. I get pumpernickel flour from King Arthur’s Baker’s Catalogue. Like other whole grains, it will spoil in time. I keep it in my freezer in a 1 gallon Ziploc bag.
- Common flour: This is also known as first clear flour. Its definition gets into esoteric grain milling stuff, but it is necessary for authentic Jewish rye breads, including pumpernickel. It also makes wonderful sourdough breads as a substitute for bread flour or a mix of white and whole wheat flours. I get First Clear flour from King Arthur’s Baker’s Catalogue.
- Cornstarch solution: Mix 1 ½ tablespoons of cornstarch in 1/4 cup cold water. Pour this into 1 cup of gently boiling water in a sauce pan, whisking constantly. Boil until slightly thickened. Set aside. It can be kept refrigerated for a few days in a sealed jar or covered bowl.
