Sourdough pizza is the biggest upgrade you can make at home. Why it tastes better, how hydration and a cold ferment work, and the heat you need to bake it.
A sourdough starter without the mystique: what it is, how to make one from scratch, why you discard, and how to keep it alive without it taking over your life.
The one bit of food science that changes how you cook: what the Maillard reaction is, why a dry surface and a hot pan matter, and how to get a real sear.
