![]() Poolish up to 8 hours in advance – 0.23% – 0.33% Logically, the more time a pre-ferment gets, the less yeast you have to use. But you have to adjust the amount of instant dry yeast you use. You can prepare your poolish up to 8 hours but also up to 16 hours in advance. Percentage of instant dry yeast in poolish For example, we use spelt, rye or whole wheat flour to add extra (and different) flavours to our bread. You can make a poolish or biga from another type of flour than the one you are using for the actual bread.Yes you can make the same bread recipe using a biga or a poolish, you just need to make sure you adjust the water content.The sugars that are released from the flour in the pre-ferment also add a nice golden colour to your bread. We like our bread that way, it gives you something to chew on. The higher the percentage of pre-ferment you use the more your bread crumb will have a nice chewy texture (but it stops at around 50%).This is especially true when using larger percentages of preferment in your final dough (think up to 50%) because over riping will kill the gluten in your preferment (the yeast will eat them all) and you will end up with a weaker and hard to handle dough. If you are working with pre-fermented doughs like poolish or biga make sure not to ‘over ripe’ your pre-ferment.Bread made with starters like poolish and biga also tends to keep better, compared to bread made from straight doughs. The primary difference between making bread with a starter and making bread with the direct or straight yeast method is that starter breads require much more time to prepare, but the flavor and texture of the bread is almost impossible to achieve with other leavening methods. Bigas can be held longer at their peak than wetter sponges, while a poolish is one known technique to increase a dough’s extensibility. Poolish is a fairly wet sponge (typically made with a one-part-flour-to-one-part-water ratio by weight), while biga is usually drier. So pre-ferments are critical for best tasting bread – You can call it a starter, biga, poolish, preferment, or sponge – they all do sort of the same job and only really differ by water content.īiga and poolish are terms for pre-ferments used in Italian and French baking, respectively, for sponges made with domestic baker’s yeast. After mixing it is allowed to ferment for a period of time, and then is added to bread dough as a substitute for, or in addition to more yeast. All of these starters are easy to prepare.Ī starter usually consists of a simple mixture of wheat flour, water, and a leavening agent (typically yeast or a sourdough culture). There are several traditional methods for creating starters for breads.
