While a Biga normally have a lower hydration, meaning being firmer in texture.īakers percentages are when all ingredients are stated as a percentage of the amount of flour used.Īutolyse is another expression bakers use. Poolish and Biga are both preferments, but a poolish is normally from equal amounts of water and flour, with a small amount of bakers yeast. Sourdough/leaven: Sourdough is one of the oldest leaving agents. This yeast can be added in the dry ingredients, but nevertheless I still activate the yeast in warm water(liquid). Instant yeast - is also commonly available in most grocery store in the US. The proofing time takes longer than the other yeasts. You need to activate the yeast in warm water before mixing the dough. Īctive dry yeast - is commonly available in most grocery store in the US. I get my fresh yeast from The New York Bakes, they ship nationwide. This is the kind I was used to from back home, but can be hard to come by here in the US. It has to be refrigerated, and have a relative short shelf-life. Not all yeast are the same, nor can they replace each other in equal amount.įresh Yeast - comes in blocks and is partially hydrated. It is possible to get semi-complete flavors in a yeast only bread, by doing a cold fermentation over 12-18 hours. You get a more complex flavor and texture, while being helped and speeded up by using yeast, compared to a yeast only bread. By using both yeast and a preferment, you get the best og two worlds. Baking with a preferment alone, you slow down the process, but you gain a lot on the flavor front. But you get speed on the expense of flavor and texture. Yeast makes it possible to bake a decent bread in a short amount of time. But it also gives a different structure to the bread. ![]() The preferment help building more complex flavors to the bread. Typically a preferment is a “pre-dough”made with yeast or sourdough starter, in advance. To get a fermentation started to make bread you need a leavening agent like yeast, some kind of preferment, or both. It’s quite impressive that these 4 ingredients can make som many different breads, even when using the same flour. ![]() I buy my fresh compressed yeast from at Copenhagen Bakery in Burlingame or online at The New York Bakersīasically bread is a combination of 4 simple ingredients: water, flour, salt, and yeast/leaven agent. You can get it hereġ pack of danish live yeast (fresh compressed yeast) is 50 g, equivalent to 1 pack of Danish dry yeast, 11.8 g.ġ pack of Danish dry yeast is 11.8 g, which is equivalent to 4 teaspoons dry yeast.ġ pack of fleischmann's dry yeast contains 7 g. Hjortetaksalt is Ammonium bicarbonate (NH₄HCO₃). ![]() You can replace potaske with Baking Soda, but the cookies won't be as crispy. This is why a scale is one of the best investments you can make for baking to avoid failure. Because the pre-ferment/leaven is filled with a lot of gas/air, it will deflate/degas, when handled. When baking with pre-ferments or leavens (sourdough), the aspect of weight versus volume measurements becomes more evident. This difference, plus the difference in water contents in the flour, will give visual and textural differences in the final product. If I weigh 1 cup of flour, I will likely not end up with the same amount as you would, if you weigh 1 cup of your flour. When you start baking, you will be told, that baking is an exact science, - and it is so true!īaking is based on specific ratios between ingredients, and using imperial/volume measurements these ratios becomes very imprecise. Baking: Weight versus Volume Measurements:
