This is possibly one of my most favorite loaf in terms of texture and the nutty flavor that the rye flour adds to it.

Levain

60 g Water 21°C

75 g Whole Wheat Baker's Flour

15 g Rye Flour

30 g Starter (ripe)

Final Dough

340 g 80.9% White Baker's Flour

60 g 14.2% Whole Wheat Baker's Flour

20 g 4.8% Rye Flour

340 g 81% Water (Reserve 20 g of the water for later)

8.5 g 2% Fine Salt

105 g 25% Levain (Ripe)

*76% Hydration

Friday 10 pm Make Levain

The night before

The night before making your sourdough, prepare the Levain and place in to a jar with a loose lid with the estimated 12 hours ripening time at room temperature.

If you prepared it too soon, simply leave it at room temperature for 2 hours then leave it in the fridge overnight to slow the ripening process. If you are retarding the Levain in the fridge, you will need to bring it back to room temperature until it is airy again before using.

Saturday 8 am Autolyze

10 hours later

2 hours before the Levain is estimated to be ready for use, mix all the flours and 320 g of the water (reserving 20 g of the water for later) until there are no dry nits of flour. At this point the mix should be quite slack and lumpy.

Cover with a tea towel and let it autolyze until the Levain is ready.

If after 2 hours your Levain is not ready, it is perfectly fine to leave the dough and water to autolyze further. Do not use Levain that is inactive.

To check if the Levain is ready for use, it should have at least doubled in volume. To test, simply gently scoop a small amount of the Levain and drop it into a jug of water. If the Levain starts to float to the surface, it means it is ready. If it sinks down to the bottom, you will need to leave it to ripen further.

10 am Add the Levain

2 hours later after autolyze

Add the Levain until it is well incorporated into the dough.

Cover and leave to rest for 30 minutes

10:40 am Add Salt

30 minutes after mixing in the Levain

Sprinkle the fine salt on top of the dough, rubbing in some of the reserved 20 g water to help it dissolve, start mixing the salt into the dough until there are no grainy bits.

Cover the dough and leave to rest for 1 hour.

11:20 am First Stretch and Fold

1 hour later after salt are added

Perform the first stretch and Fold. Cover and rest for 30 minutes.

11:50 am Second Stretch and Fold

30 minutes later

Perform the second stretch and Fold. Cover and Rest for 30 minutes

12:15 am Third Stretch and Fold

30 minutes later

Perform the third and final stretch and fold. Cover and rest for 1 hour.

Note: if after an hour the dough looks like it is quite slack, you can do another stretch and fold and let it rest for another 30 minutes.
