    Starter to First Loaf

    Your first open-crumb loaf

    14 Steps, about 24 minutes each. Total beginners. You need a kitchen scale and an oven. No baking experience needed.

    1. Chapter 1: Grow your starter. A starter you feed every day and know how to read, and your first bake: a tray of crisp discard crackers.
    2. Chapter 2: Your first loaf. A ready starter, your first real sourdough loaf, and the skill to read its crumb and know what to change.
    3. Chapter 3: Make it yours. A starter that fits your week, a second loaf with one improvement you chose, and bread you can share.
    1. 1
      Mix your starter
      A jar of flour and water that will become your starter, marked and in a warm spot.

    Bakery Breads

    Batards, bagels, focaccia and your own loaf

    20 Steps, about 50 minutes each. Bakers who finished Level 1 or can already bake a decent sourdough boule and want to bake everything else a bakery sells.

    1. Chapter 1: The bakery batard. A levain built on schedule, a wetter dough handled with coil folds, and a tall batard with an ear.
    2. Chapter 2: Score, grain and flavor. Decorative scoring, a hearty whole wheat loaf, a cheese and jalapeño loaf, and a bake schedule that fits your week.
    3. Chapter 3: Beyond the loaf. Focaccia, a soft sandwich loaf, chewy bagels, pizza night and sourdough cinnamon rolls.
    4. Chapter 4: Your signature loaf. Baguettes, a crumb you can read and fix, your own formula on paper, and a signature loaf shared with friends.
    1. 1
