📝 Preparation Steps
1
Directions for Day 1
2
Clean
3
Sanitize a large mason jar and zero it out (or “tare”) on a kitchen scale set to measure grams.**
4
Add 75g of all purpose flour to the jar. For me, this was ½ cup of flour.
5
Pour
6
Zero out the scale again by pressing the “tare” button, and add 75g of water. If you don’t have a kitchen scale, just use a 1:1 ratio of water to flour throughout the entire process. So, if you add ½ cup of flour, add ½ cup of water.
water (or ½ cup water)* ($0.00)75 g
7
Mix
8
Stir the flour and water together with a clean spoon and cover the jar with a piece of cheesecloth, a coffee filter, or a clean, dry paper towel.*** Secure the cloth with an elastic or butcher twine. You want to make sure you give it a good stir—oxygen is necessary when making sourdough starter!
water (or ½ cup water)* ($0.00)75 g
9
Rest
10
Let it sit on the counter for ⏱️ 24 hours in a 75-80 degree warm spot. I like to make a little line on the glass jar with a permanent marker so I can see how much my starter grows as it develops over the course of the week.

Directions for Day 2
12
Stir
13
Give your starter a stir with a clean spoon. Remember, oxygen is good for the process! Let it sit for Day 2 undisturbed in the 75-80 degree warm spot while it develops a bit more. You may see bubbles on day 2, or you may not. Trust the process!
14
Directions for Day 3 to (potentially) Day 14
15
Remove
16
It’s feeding time! Remove half of the sourdough starter from the jar. This is your discard! Use a spoon and scoop it out…eyeball what’s “half”, or use your scale. Remember to factor in the weight of the empty jar if you’re using a scale to get the exact number.
17
Mix
18
To the jar, add 75g of all-purpose flour and 75g of water. Mix with a clean spoon until completely smooth. It will look like thick pancake or muffin batter.
all-purpose flour (or ½ cup flour) ($0.07)75 gwater (or ½ cup water)* ($0.00)75 g
19
Cover with a coffee filter, paper towel, or cheese cloth with an elastic band and let it sit on the countertop for ⏱️ 12-24 hours.
20
Repeat these steps over and over until it has doubled in size (at least 250-300g), has consistent bubbles, smells pleasantly yeasty, and appears to be the texture of marshmallow fluff!
21
Name your starter! It’s the “mother” of every loaf of bread you’ll make from here on out…Plus, it’s bad luck if you don’t! (Mine are named Agnes and Rita after my grandmothers!)
