Remove contents from the packet into a large, glass mason jar (32 oz. or larger). Mix with 20 grams of warm, filtered water (80-85°F). Do not use distilled or reverse osmosis water. Allow to sit for 1 hour to dissolve.

Mix up the starter & water. The starter should be completely dissolved (or almost completely dissolved) in the water. Add 15 grams of unbleached bread flour. Mix until you have a thick paste.
Gently place the mason jar lid on top of the jar so that air can still get to the starter. Leave it alone & untouched for 24 hours.

To your mason jar, add 30 grams of bread flour & 30 grams of warm water. Mix well, gently place the lid on top of the jar, & leave it alone for another 24 hours.

To your mason jar, add 60g bread flour & 60g warm water. Mix, gently place the lid on top, and leave it alone for another 24 hours.

6. Discard all but 50 grams of the starter. You can toss the discard or save it for discard recipes. Feed it 50 grams of bread flour & 50 grams of warm water. Mix & gently cover with the lid once again. If you want to make my classic sourdough loaf today, do 90 grams of starter, flour & water instead of 50 grams. If you are just trying to activate the starter or if you are making a different recipe that does not require too much active starter, 50 grams should be plenty.

5-6 hours after feeding, your starter should have doubled in size and is nice and bubbly.

Perform the “float test”. Take a teaspoon or so of starter and drop it into a small cup or bowl of water. If it floats, it’s ready to use!
