Is 55% hydration right for Medium Rye Flour?
Medium Rye Flour's workable hydration range is 80–95%. Its absorption multiplier is 1.08× bread flour. 55% is below Medium Rye Flour's typical range. The dough will be stiff and hard to fully develop. Consider moving up to 80% for better extensibility.
Absorption math for Medium Rye Flour at 55%
A recipe written for bread flour at 55% hydration, when substituted with 100% Medium Rye Flour, becomes 59% effective hydration (because Medium Rye Flour absorbs 8% more water). Do NOT knead rye dough (tears pentosan structure). Mix to incorporate, then rest. Very short bulk ferment (2-3 hours at 76°F) — rye ferments fast. Wet hands for shaping. Use a pan or tight banneton. Bake at higher initial temp (500°F) for 15 minutes, then reduce. Internal temp 205-210°F for doneness.
Technique at 55% hydration
Stiff dough, easy to handle. Use stand mixer for enriched versions. Low-hydration doughs tolerate mistakes well — good starting point for new bakers. Appropriate for pan-shaped loaves, enriched breads, and styles requiring dense texture like bagels and pretzels.

How the math works
Total water = flour × hydration %. Your levain contributes 50 g flour + 50 g water — both count toward the totals. You add only the remainder as fresh flour and water.
Salt % is computed on total flour weight, not final-dough flour.
