Overview
Sesame seeds are a small, high-fat, flavor-concentrated ingredient used to add aroma, texture, and a toasty note to sourdough. They contribute surface crispness when applied as a crust topping and a nutty, savory flavor when mixed into the crumb. Sesame's oils also slightly soften crust and can change dough handling when used in large quantities [1].

Troubleshooting & Tips
Issue: Dough feels greasy or weak when seeds are added. Solution: Reduce added oil elsewhere (tahini) and return to slightly lower hydration; increase fold frequency to build gluten strength. Issue: Surface seeds burn during bake. Solution: Lightly toast seeds beforehand to stabilize color, or reduce rack height and shield crust late in bake with foil. Issue: Uneven seed distribution. Solution: Add seeds during final folds in small portions and use a large mixing bowl so seeds can be folded in without spillage [1][2].
Selection And Storage
Choose raw, unblanched sesame for maximum flavor; hulled (white) seeds are milder, while unhulled (brown/black) seeds give more bitterness and color. Store in an airtight container in the refrigerator for long-term storage to prevent rancidity from the seed oils. For starter maintenance or seed soaking, use a clean glass jar for starter or a clear straight-sided container to observe changes [1][2].
Toasting And Flavor
Light toasting dramatically improves sesame's aroma and flavor by driving Maillard reactions and volatilizing desirable aromatic compounds. Toast in a dry skillet over medium heat, stirring until fragrant and lightly colored (30–90 seconds), or toast in a 175°C (350°F) oven for 5–8 minutes watching closely. Toasted sesame increases perceived umami and compensates for weaker flours; cool seeds fully before adding so they don't affect dough temperature or fermentative activity [1][2].
Hydration And Dough Adjustment
Sesame seeds absorb little free water compared with whole grains, but their oil content affects dough feel. When adding up to 10% seeds by flour weight, increase dough hydration by ~1–2% (example: for 500 g flour, add 5–10 g extra water) to preserve extensibility; above 10–15% consider 3–5% extra water and additional folds to build strength. Use a digital kitchen scale for precise adjustments and an instant-read thermometer to track dough temperature during warm toasting seasons [1][2].
How to Add Sesame to Dough
- There are three reliable methods to incorporate sesame into sourdough:
- Surface topping: Apply seeds to loaf exterior after shaping and wetting the surface with water or an egg wash for adhesion; gives crisp, visual crust contrast.
- Final-fold addition: Mix seeds into the dough during the last set of stretch-and-folds so distribution is even without overworking the gluten.
- Soaked paste / tahini swirl: For an intense sesame layer, stir toasted ground sesame (tahini) into a small portion of dough or use as a swirl — reduce added oil elsewhere and be aware tahini increases softness in crumb and may slow oven spring.
- Use a dough scraper when folding to avoid losing seeds on the bench [1][2].
Practical Recipes & Tips
Simple formula: 500 g strong bread flour, 100 g mature sourdough starter (20% inoculation), 350–375 g water (70–75% hydration baseline), 10 g salt, 30–50 g toasted sesame (6–10% of flour weight). Add seeds during the last 2–3 folds or sprinkle on top before proofing in a banneton proofing basket. For a crust with embedded seeds, roll shaped dough gently in seeds placed on parchment before final proof on parchment paper for easy transfer to a Dutch oven or cast iron pot for baking. Monitor oven spring and crust color; sesame browns faster so lower top-heat slightly if crust darkens too quickly [1][2].
Nutrition And Functional Effects
Sesame seeds supply fats (notably polyunsaturated), protein, fiber, calcium, and antioxidants (sesamol, sesamin). In sourdough, small percentages negligibly impact fermentation, but oils can lubricate crumb making slices softer and slightly reducing chew. Because of the oil content, sesame can promote faster surface browning in the oven [1][2].
