why do my loaves NEVER have that crackly crust? soft tops every single time

Probably nothing is wrong - check WHICH breads you're baking first, because crust is a recipe feature before it's a technique.

Enriched doughs - pav, milk bread, anything with good fat, milk and sugar - bake SOFT by design. The fat tenderises the crust chemically and no oven trick overrides it. If your repertoire is the soft-bread family, you've been succeeding, not failing.

The crackle belongs to LEAN doughs: flour, water, salt, yeast, little else. Then two conditions build it - STEAM in the early bake (it keeps the surface flexible for maximum spring, then gelatinises it into that thin glassy shell) and HIGH heat, 230-250°C territory. At home the covered-pot method delivers both: preheated heavy pot, lid on for the steam phase, lid off to colour and crisp.

The singing as it cools - that crackle soundtrack - is the crust contracting. It only performs for lean, steamed, hot-baked loaves.

So: pick a lean recipe, get the pot ripping hot, and your kitchen finally gets its concert 🎵
