Global — the earliest leavened bread evidence dates to ancient Egypt (c. 3000 BCE); wild yeast fermentation is the original bread technology; sourdough declined in the 20th century with commercial yeast but experienced a global revival from the 1970s (San Francisco sourdough as the contemporary reference point) and was dramatically accelerated by the COVID-19 pandemic home baking movement of 2020 · Global Bakery — Breads & Pastry
Eaten warm from the oven with cultured butter; as the base for avocado toast, tartines, and open sandwiches; the flavour spectrum from mild San Francisco-style lactic tang to aggressively sour German-style Roggensauerteig (rye sourdough) represents the full range; paired with cheese, charcuterie, or as the bread for a ploughman's lunch
Baking an under-fermented loaf — under-fermented dough collapses in the oven and produces a dense, gummy crumb; the poke test (an indent slowly springs back halfway) is the reliable guide Opening the Dutch oven too soon — the steam environment (first 20 minutes with lid on) is what allows oven spring before the crust sets; removing the lid early produces a flat, thick-crusted loaf Over-proofing — over-fermented dough has exhausted its gas and gluten strength; it spreads flat rather than rising; shaping and cold-retarding in the refrigerator provides a controlled window Cutting into a hot loaf — the crumb continues to set as the loaf cools; cutting while hot produces a gummy, undercooked-feeling interior; wait a minimum of 1 hour (ideally 2–3) after baking
