Abigail’s Oven · Spanish Fork, Utah
Sourdough doesn’t have to be learned all at once.
Abigail’s Oven is a family-run bakery in Spanish Fork, Utah. We make sourdough the old-fashioned way: flour, water, salt, a living start, and time.
Want to make the same kind of bread we bake at Abigail’s Oven? There’s more than one way to get started.
Start with the free calculator and figure out the numbers behind your loaf. Bring home the same mother culture we use in the bakery. Want a little extra guidance? Add a quick video to walk you through your first loaf. Or, if you’re ready to really dive in, spend three live days baking alongside Martha.
Start wherever makes sense for you.
Four ways to begin
As much help as you want. Or as little.
There’s no right way to start baking sourdough. Use what you need, skip what you don’t, and choose the place that feels right for you.
Not sure where to start? Our free calculator helps you make sense of the numbers behind your loaf - from flour and water to hydration, temperature, and timing.
Take home the same mother culture we use to bake bread at Abigail’s Oven. It’s the same place we start.
Get our bakery mother culture plus a short, simple video to help you through your first loaf.
Spend three days baking alongside Martha and make nine loaves while learning what water, warmth, and time actually do to your bread.

AO Recipe and Hydration Calculator
Good sourdough begins with a few simple things: flour, water, salt, a living start, and enough time.
Our free calculator helps you work out the numbers for your loaf, including hydration, temperature, leaven, salt, resting, and folds.
Use the calculator completely free, with no sign-up required. If you want to save your preferences, we’ll just ask for your email so we can remember them and occasionally send you helpful tips and offers. Otherwise, jump right in and start baking.
Bring our sourdough start home
Dehydrated Sourdough Start
If you want to bake with the culture behind Abigail’s Oven bread, we’ll send some your way.
This is a dehydrated mother culture from our bakery—the same culture we use to make the bread you’ll find at our bakery. It’s not commercial yeast, and it’s not a jar of wet starter making its way through the mail. It arrives dehydrated and ready for you to bring to life.
Wake it up. Feed it. Watch it come alive. Then make it yours.
We’ll include everything you need to get started, including care and activation instructions. Mother cultures ship every Tuesday. Order by Saturday at 5:00 p.m. Mountain Time to make that week’s shipment. Shipping is calculated at checkout.
If your culture doesn’t wake up the way it should, reach out. We’ll make it right.
Want a little help with that first loaf?

- Wake the start.
- Watch it bubble.
- Bake the first loaf.

Sourdough Unlocked: Never Guess Again
October 22–24, 2026 · Live online · $299
For three days, Martha Levie will bake from the Abigail’s Oven kitchen while you bake in yours.
You’ll make three loaves a day—nine loaves in all. You won’t simply repeat the same recipe nine times.
On Thursday, you’ll change the water. On Friday, you’ll work with warmth. On Saturday, you’ll change the timing.
Then you’ll see what happens. You’ll compare your loaves, notice the differences, and start to look at a loaf that didn’t quite turn out and ask yourself: what should I change next time?
You can watch Martha and follow along at your own pace, or bake right alongside her. There are beginning, intermediate, and advanced paths woven into the same three days, so you can work at the level that makes sense for you. And if you miss a session, the recordings will be waiting for you.
Your $299 seat includes:
● Abigail’s Oven starter
● Three days of live instruction with Martha on Youtube
● Live chat during the sessions
● Recordings to watch afterwards
● Written instructions and prepare-ahead videos
● A complete materials list
● Access to the recipe calculator
● An evening Q&A with Martha and Allen
Your class starter and its shipping are included with your seat. Class starters ship by October 18, 2026, so there’s no need to purchase the $19 starter separately. Guests can attend free, but each guest needs to purchase their own $19 starter.
Not sure if it’s for you? Contact us before the class begins for a full refund.
Nine loaves. Then you’ll know what to change next time.
This bakery
From our bakery to your kitchen.
Abigail started selling bread from a little red wagon. Our family built Abigail’s Oven from there. Today we’re still a family-run bakery here in Spanish Fork, Utah, baking sourdough in Dutch ovens.
We love making bread for people. We also love the moment when someone realizes they can make it themselves.
You don’t need every tool on this page to begin. You don’t need a class before you’re allowed to bake. And you don’t need to know everything about sourdough before you put flour and water in a bowl.
Start with what helps. Then bake a loaf.
A few questions

Is the $29 bundle Sourdough Unlocked: Never Guess Again?
No. The quick-start video is a short help for getting started. The Sourdough Unlocked: Never Guess Again is a separate live class, October 22–24, 2026, where you bake nine loaves with Martha.
Does Sourdough Unlocked: Never Guess Again include a sourdough start?
Yes. A starter from Abigail’s Oven and its shipping are included with the $299 class seat; starters ship by October 18, 2026. Guests attend free and purchase their own $19 starter.
