What is ancient grain einkorn flour?
Modern wheat is very different from what our ancestors were baking with. Einkorn flour has a different structure and is much easier to digest than modern wheat. And because of the changes, many people are sensitive to flour. Haven’t you always wondered why so many gluten allergies?
Problems eating wheat may include…
- bloating
- inflammation
- headaches
- blood sugar levels
- allergies
Upon discovering Einkorn flour, it has changed our baking once again. When realizing we had challenges when baking with white flour, we changed to gluten-free for a while, but I wasn’t fond of gluten-free flour.
Then, we tried grain-free and almond flour is great for some baked goods, but for some things I wanted a light fluffy taste. Then, I discovered Einkorn. This flour is not hybridized and is the original grain. I cannot rave enough about how great this flour is.
Wheat flour has been hybridized and changed and is a very different wheat today. The wheat stalk is shorter, bigger, and heavily sprayed.
- no bloating
- no headaches
- no foggy head

Can you use wheat or white flour instead of einkorn for sourdough starter?
Yes. Before I realized we were very sensitive to white/wheat flour I used to make my own homemade sourdough starter from white flour. In general, white flour seems to do better for the starter. You may want to use regular white flour instead of einkorn white flour for a cheaper choice.

Instructions for making homemade einkorn sourdough starter
Day 1–Day 2 mornings and night 12 hrs apart
- heaping 1/4 cup einkorn flour
- 1/4 cup filtered water
- mix well with a wooden spoon and loosely place a lid on top. or plastic wrap. Set out of direct sunlight. Mine sits in my cabinet
Note: You want a consistency of a thick batter. Adust the starter if needed.
Watch as it does its magic……You may start to see more bubbles.
Day 3
Discard half and feed. You can put the discard in the fridge. If I rush and try to use the discard before day 3 my sourdough biscuits aren’t as good.
Day 4
Same as days 1-2
Day 5
Discard half and feed the leftover starter. Put discard in the fridge to use in recipes.
Day 6-7 You will have an active yeast but you can take it to day 8 and it will be stronger.
Repeat days 1-2
Day 8
Einkorn sourdough starter is ready
Some have suggested feeding every 24 hrs, but in my high humidity climate in the summer, I find feeding it 1-2 times daily is necessary or I end up with a bad starter.

Hello!
I am new to this, so I’m going to just pop out a question.
Using 100F filtered water, 45g and
Einkorn 60g
My instructions followed to let it rest 48 hours. Our kitchen is 70-77F right now (Sonoran desert).
I grew some mold.
If I’m understanding your instructions I should have tended to it every 12 hours. Is that correct?
I am guessing that the temp is too warm? Or maybe not enough water?
Thanks for any help.
I just started a new batch 50g water, 60g einkorn and I stored it in a cabinet further away from the stove.
When it’s really high humidity, I have to tend to it every 12 hrs. On cooler days, I have gone longer in between feedings. And I’ve never used hot water to start, but I don’t think it would matter as it would cool quickly. My filtered water from the refrigerator has worked fine. Hope that helps! Good luck!
Hi…………….I’ve tried this too many times and just want to make absolute certain I’ve got your instructions correct…..
So on day five you don’t feed at all? Just discard?
And on day 6 and 7 you don’t discard at all? When do you discard again ? Other recipes I’m familiar
with you discard regularly. Thx for any suggestions!! :))
Hi! Days 3 and 5 are the same. I discard and feed on days 3 and 5. The other days, I feed. Print out the recipe card at the end of the post for reference. I updated the instructions to make it clearer
So you don’t have amounts for what u call ‘feed’…are u saying after discarding on day 3 u are ALWAYS Feeding w the same 1/4 c. Combo of flour&water?
( Even though u are just approximating 1/2 to empty on discard days and the batch is getting bigger over time?)
Thanks!
Yes, I feed about 1/4 cup each time. But you really don’t have to use the exact measurement. Just make sure when adding water you have a thick batter. Yes, it will grow and start having a yeasty aroma. Make sure you have a container that allows for growth.
