Fruit Yeast Water: Q & A | Baking with Fruit Yeast Water
updated
As a quick note, we want to say that this is definitely not meant to be a negative video about sourdough, but rather, it's a deeper look at the many claimed health benefits that can often mislead people into thinking that a sourdough bread is healthier than it really is. Because while sourdough does make better tasting bread that lasts longer, it doesn't necessarily make it the healthiest option available.

Once a lucrative business in Japan, the Premium Shokupan trend has since cooled and may have become more of a problem rather than an opportunity for business owners. Meanwhile, in France, the crisp and crusty baguette, as we know it, may become very different as consumers change their preferences.

Here, I'm going to make the argument for preferments, based on science of course. We'll talk about why pre-ferments are different from a long straight dough fermentation. We're also going to cover what kind of pre-ferments there are and how we can best use them. Watch the video for more!

We're going to dive into the history and some of the science behind frying the youtiao. While the youtiao aren't as puffy as they could be with baking powder, their flavor and crunch is absolutely impeccable, and the youtiao may also be healthier thanks to the lower acrylamide content from fermentation. Watch the video for more on making these yummy and super crisp youtiaos!

To achieve these characteristics, the baking industry has a wide range of bread improving additives, many of which you can find on the ingredients list of a loaf at the supermarket. However, as home bakers, we try to avoid these sort of additives, instead going for more natural options, one of them being sourdough.
Sourdough bread is the oldest form of leavened bread, this method has been passed on for centuries, and for good reason. Sourdough influences practically all aspects of bread quality in a generally positive way. There are numerous health benefits associated with using sourdough and the bread is well known for its remarkable taste.
The greatest obstacle to making sourdough, though, is probably how it resists the normal recipe standardization we're so used to, it requires an understanding of the sourdough starter and its specific traits. There are quite a few parts of sourdough bread baking that differ greatly from other kinds of bread baking, and that's part of what this video aims to talk about.
In this video, we're going to delve into sourdough and how to make sourdough bread. We're going to show you how to make a high quality artisan sourdough bread, with a beautiful open crumb and delicious crisp crust, using all the relevant scientific facts. We'll also go into detail on the live cultures residing in a sourdough starter, wild yeasts and bacteria, as well as how to give them a conducive environment to grow. Because each sourdough starter can be different, this video gives you all the information you need to fully understand and make the best use out of your starter. Watch the video for more, enjoy!

Such an ideal fresh baguette is the ultimate end goal of many bakers, including us. This video is a detailed guide on how to make better homemade baguettes with the basic tools we have on hand, and of course, based on science. To achieve that, we're using poolish and tangzhong, the first is for increased taste and aroma, and the latter is for a softer texture, to enable the baguettes to last for longer, and also prevent them from drying up in the oven, due to the prolonged baking. There are many important steps in the making of these baguettes, which we're going to be covering in this video, including long fermentation, proper shaping, and the right way to bake the baguettes for the perfect crumb firmness and crust brittleness. These baguettes are crispy on the outside, soft and chewy on the inside, and last for a good while, although they're always gone within an hour here! Watch the video for more!
Note: this video was made with clips from numerous batches.

effect of gelatinized starch on baking bread1. Food Sci.
Technol. Res., 11, 194-201 (2005).
We try to address frequently asked questions (FAQ) about tangzhong/yudane that most beginners or even experts in bread baking will wonder about before adding it to their bread dough. With all the information floating around online, it can seem to be very confusing and complex, but in reality, the underlying principles are relatively straightforward. We pored over many research papers on the history, origins and applications of tangzhong/yudane, and the science behind starch gelatinization. For these purposes, we've looked at papers in Japanese, Chinese, and English, to get a really good view of the research.
There is a lot of misinformation spread around on this bread-improving technique, which is part of what we aim to tackle. The real key to the method whether it's called tangzhong, yudane, or water roux, is starch gelatinization, which we cover in depth in this video to show you how different methods ultimately lead to this same goal. Many methods online do not seem to get the full benefits out of using gelatinized starch in bread to get softer and tastier bread.
This video is going to be a deep dive into the science and research of gelatinized starch in bread. By the end of the video, you'll come away with plenty of information on tangzhong/yudane, perfect for making the soft and delicious bread of your dreams.
