Whole grains contain phytic acid, which binds iron, zinc, calcium, and magnesium. Long sourdough fermentation activates wheat phytase and frees those minerals. Here is the biochemistry, with citations.
A 5,000-year history of sourdough bread — from accidental Egyptian fermentation through Roman panis, French levain, San Francisco Gold Rush wild yeast, and the modern revival.
The chemistry of water in bread baking -- calcium, magnesium, chlorine, chloramine, pH, and when filtered water actually helps your dough.
Salt strengthens gluten, controls fermentation rate, inhibits proteases, and enhances flavor. The full science of why 2% salt is the baker's standard.
The 4 mechanisms behind oven spring — enzyme acceleration, CO2 solubility, vapor pressure, and thermal expansion — plus steam, scoring, and diagnostics.
The science of fat in bread dough — how butter coats gluten strands, why timing matters, and the difference between butter and oil in enriched breads like brioche.
The real science behind bread flour and all-purpose flour — protein content, water absorption, gluten development, and when each one matters.
Staling is starch retrogradation, not moisture loss. The refrigerator accelerates it. Here's the science, storage rules, and why toasting reverses it.
A complete guide to bread hydration -- what baker's percentage means for water, how it changes dough behavior, and why the recipe number isn't always right.
The real microbiology of sourdough starters -- specific bacteria and wild yeasts, why geography doesn't matter, and how to control flavor.
The chemistry behind bread crust flavor -- amino acids, reducing sugars, and heat create hundreds of flavor compounds above 250 degrees F.
Everything happening inside your dough -- glycolysis, CO2, enzyme activity, yeast behavior, and the temperature rules that control it all.
The real science of gluten in bread -- glutenin, gliadin, disulfide bonds, and why different flours make different bread.
