1,000 grams of flour, 680 grams of water, 20 grams of salt, and 20 grams of fresh yeast. In baker’s percentages, that can be stated as 100 percent flour, 68 percent water, 2 percent salt, and 2 percent fresh yeast. (Note that 3 grams of fresh yeast equals 1 gram of instant yeast, so this would equate to about 7 grams of instant yeast.)
