Is 55% hydration right for Light Rye Flour?

Light Rye Flour's workable hydration range is 6880%. Its absorption multiplier is 1.03× bread flour. 55% is below Light Rye Flour's typical range. The dough will be stiff and hard to fully develop. Consider moving up to 68% for better extensibility.

Absorption math for Light Rye Flour at 55%

A recipe written for bread flour at 55% hydration, when substituted with 100% Light Rye Flour, becomes 57% effective hydration (because Light Rye Flour absorbs 3% more water). Handles closer to wheat than medium or dark rye — light stretch-and-folds are fine at low percentages. Keep the bulk ferment a touch shorter than an all-wheat dough; rye enzymes speed fermentation. Above ~40% rye, switch to no-knead rye handling (mix, rest, wet hands, tight banneton).

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.
