   ["Mix the flours to make 1250 grams of 50/50 flour blend. Use this blend to feed your culture and develop your starter.", "To make your starter, in a medium bowl, place 300 grams of slightly warm (80 to 85\u00b0 F, 26 to 29\u00b0 C) water. Add 315 grams of flour blend (reserve the remaining flour blend), and mix with your hand or a wooden spoon to combine until the mixture is free of any dry bits. Cover the mixture with a clean, dry kitchen towel or cheesecloth and let stand at warm room temperature until bubbles start to form around the sides and on the surface, about 2 days. It's important to maintain a warm temperature. Let stand another day to allow fermentation to progress a bit. More bubbles should form. This is your starter. It will smell acidic and slightly funky. At this stage it's time to train your starter into a leaven by feeding it fresh flour and water at regular intervals.", "Feed the starter: Transfer 75 grams of the starter to a clean bowl and discard the remainder of the starter. To the 75 grams of starter, add 150 grams of the 50/50 flour blend and 150 grams warm (80 to 85\u00b0F, 26 to 29\u00b0C) water. Mix to combine; it should have the consistency of pancake batter. Repeat this feeding process once every 24 hours at the same time of day, always transferring 75 grams of the starter to a clean bowl and discarding the remainder, then adding the flour and water and re-covering the bowl with a clean, dry kitchen towel after each feeding and letting the mixture stand at warm room temperature. The batter should start to rise and fall consistently throughout the day after a few days of feedings. As the starter develops, the smell will change from ripe and sour to sweet and pleasantly fermented, like yogurt. Once this sweet lactic character is established and the fermentation (the regular rise and fall of the batter) is predictable, a few days to one week, it's time to make the leaven from this mature starter.", "Leaven is the portion of prefermented flour and water that will go into your final dough and raise the whole mass during the bulk (first) and final rises. Two days before you want to make bread, feed the matured starter twice daily, once in the morning and once in the evening (the process described above) to increase fermentation activity. When you are ready to make the dough, discard all but 1 tablespoon of the matured starter. To the remaining 1 tablespoon, add 200 grams of the 50/50 flour blend and 200 grams warm (80 to 85\u00b0F, 26 to 29\u00b0C) water. This is your leaven. Cover and let rest at moderate room temperature for 4 to 6 hours.", "To test the leaven's readiness, drop a spoonful into a bowl of room temperature water. If it sinks, it is not ready and needs more time to ripen. When it floats on the surface or close to it, it's ready to use to make the dough.", "To maintain the leaven for regular use, continue feeding daily as described above. To save leaven for long periods without use, add enough flour to make a dry paste and keep covered in the refrigerator. When you want to use it again, keep at warm room temperature for at least 2 days and do three to four feedings to refresh and reduce the acid load that builds up while it is stored in the refrigerator.", "To make the dough/premix, in a large mixing bowl, combine the flours and wheat germ. In a second, large mixing bowl, add 700 grams of water. Add the leaven to the water and stir to disperse. Add the flour mixture to the liquid-leaven mixture and stir to combine until no dry bits remain. Cover and let the premix rest for at least 30 minutes and up to 4 hours to hydrate during this rest period, taking care to keep the mixture where it is at warm room temperature. After autolyse (or the rest), add the salt and the remaining 50 grams of slightly warm water, folding the dough on top of itself to incorporate.", "For the bulk rise, transfer the dough to a medium bowl and keep covered to maintain a warm dough temperature of 80 to 85\u00b0 F (26 to 29\u00b0 C) to accomplish the first rising time, 3 to 4 hours. During the bulk rise, the dough is developed by folding and turning it in the container. Fold the dough every 30 minutes for the first 2 1/2 hours of bulk rising. To do a fold, dip one hand in water, grab the underside of the dough, stretch it out, and fold it back over itself. Rotate the container one-quarter turn and repeat three to four times. When you are folding the dough, note its temperature to the touch and how the dough is becoming aerated and elastic. Fold in the cooked oat porridge, almonds, and almond oil gently by hand after the first two series of turns, about 1 hour into the bulk rise. After 3 hours and six foldings, the dough should feel aerated, billowy, and softer. You will see a 20 to 30 percent increase in volume. If not, continue bulk rising for 30 minutes to 1 hour longer.", "When the dough is 20 to 30 percent increased in volume, billowy, and elastic, remove it from the container with a dough spatula. We don't \"punch\"" the dough down tode-gas at Tartine. We strengthen the dough by using gentle folds and turns. As flavor develops during the first rising
