Here’s how we’re gonna do this👇🏼

1 - BIRTH

Start with an empty jar and build your starter from scratch —without panicking over every weird smell or quiet day.

2 - READ

Stop blindly following the clock and start understanding what YOUR starter is actually telling you.

3 - BAKE

Learn when your starter is truly ready, then turn that little jar into your first loaf.

4 - SUSTAIN

Learn how to care for your starter in real life so you can actually keep baking after Starter School ends.

SUM'S SOURDOUGH STARTER SCHOOL 🤎

Real Students, Real Sourdough Success

Don't just take my word for it!

Here's what other students have experienced while learning to make sourdough with me.

THE FACE BEHIND THE FLOUR 🤎

Hi, I'm Sum! 👋

I didn't wake up one day magically knowing how to make sourdough. I Googled everything, watched endless TikToks, and questioned pretty much every bubble in my starter.

Having someone to help me figure things out made all the difference. That's exactly why I created Starter School.

My goal is to help you understand your sourdough so you can confidently do it yourself. 🤎

BUT I STILL HAVE QUESTIONS!

  • If you already have an established sourdough starter, Starter School may not be what you need! 🤎

    Starter School is designed for the brand-new sourdough beginner who wants to build a starter from scratch, learn how to understand it, and eventually turn it into their first loaf.

    Already have a starter and feel comfortable with the basics? Come hang out with us in Sum’s Sourdough Kitchen Club instead! That’s where we keep baking together with new recipes, tutorials, experiments, and a community to help along the way. 🍞🤎

  • PERFECT😂 We’re starting with an empty jar. You do not need to know a damn thing about sourdough before you walk through the door. That’s what I’m here for.

  • NOPE 👏🏼 You’ll need a few basic supplies and ingredients, but you absolutely do not need to turn your kitchen into a sourdough laboratory. 😂 I’ll tell you what you actually need—and what you can skip.

  • Life happens. Kids happen. Work happens. You forget about the jar. 😂 That doesn’t mean you failed Starter School. We’ll figure out where your starter is, what it needs, and how to move forward from there.

  • November 9, 2026! 🍞🤎 Starter School is completely self-guided, meaning there's no set schedule or pressure to keep up! You'll have step-by-step lessons to follow at your own pace, so you can begin your sourdough journey whenever the timing feels right for you!

  • You do NOT need to stand over your starter all day. 😂 I’ll teach you how to read what’s happening and work sourdough into your actual life instead of feeling chained to your jar.

  • You absolutely can. 🥹🤎

    Starter School is where you learn how to actually DO sourdough—but you definitely don’t have to leave me after that. 😂

    If you want to keep baking together, Sum’s Kitchen Club is where we’ll keep the fun going with new things to bake, continued support, and plenty of reasons to keep that starter alive. 🍞

    Kitchen Club is a separate membership, and you’ll have the option to join when the time comes. 🤎
