Westphalian dense rye loaf — 100% coarse rye, 16-24h slow-bake at 100-120°C. Near-black, faintly sweet, the long-keeper of German bread.
Westphalia, c. 1450 — Soest and the surrounding monasteries baked it in tin-lined chambers fired by the residual heat of larger ovens, a frugal way to use the falling temperature. The name's etymology is contested: 'Pumpern' (Low German for breaking wind) plus 'Nickel' (devil's nickname) is the most likely; 'pain pour Nicol' (bread for Napoleon's horse) is folk legend.
Mestemacher and Pumpernickel-Bäckerei Haverland in Soest still bake to the 1450s schedule. A vacuum-packed slab keeps 6 months unopened. The American 'pumpernickel' (NYC deli, with caraway and added molasses) is a different bread under the same name — closer to a sour rye.
Cocoa-dark, oily-dense, slices thin like rye terrine. Tastes of molasses and toast without any added sugar — that's the Maillard from the long bake. Tangy-mineral, no chew, eats best with butter and herring or hard cheese.
Steam-baked in lidded tin pans inside a closed chamber at 100-120°C for 16-24 hours. The low temperature converts rye starch to dextrins (browning) without the crust burning. No yeast in traditional Westphalian; sourdough plus the long Maillard is the entire leavening and flavor system.
Variations
Westfälischer Pumpernickel (24h bake, no yeast, Soest standard); Vollkorn-Pumpernickel (with whole rye berries); Mestemacher industrial (commercial 16h, slightly sweetened); American deli pumpernickel (NYC sour rye with caraway and molasses, distinct lineage).

Ingredients
Serves 12How it's made
6 steps · 23 min active + 2 days 4 hours waiting
- 110 min
Mix 600 g coarse rye flour, 400 g cracked rye, 20 g salt, 30 g molasses, 100 g sourdough starter, 600 ml warm water.
- 28 min
Knead until cohesive (dough will be very sticky), 8 min.
Watch outRye dough stays tacky and heavy — don't chase a smooth springy ball; knead just until it holds together.
- 3720 min
Bulk ferment 12 hours at room temperature.
Watch outAfter the long room-temp ferment the dough should smell sour and look puffed and bubbly — that's the sourdough doing all the leavening.
- 45 min
Shape into a buttered deep Pullman pan.
- 5960 min
Bake covered at 120 °C for 16 hours.
Watch outKeep it covered and low the whole bake — you want the crumb to slowly darken sweet, not the crust to scorch.
- 61440 min
Cool completely 24 hr before slicing very thin.
Watch outLet it go stone-cold a full day before slicing — cut warm and it drags into a gummy smear.
