bread. Bread flour may be white, brown or wholemeal. Plain or soft flour has poorer quality proteins and produce a lower percentage of gluten ((7-9%). As the gluten is formed from poorer quality proteins it is less elastic and tends to snap. This means that the strands can’t form a mesh to trap the gas bubbles resulting in a crumbly texture. However, this property makes this flour perfect for making cakes and pastries. Self-raising flour is basically plain flour with added raising agents and is primarily used for cake baking. However, it can be used in some non yeasted breads such as soda bread. Malted grain flour is a type of blended flour. Malting is used on grains to encourage the production of sugars and these are dried and roasted to capture the sweet flavour. These grains are then blended into strong flour (normally brown) to produce a variety of breads such as malted grain and cobber. Durum (or 00) flour is the final type of wheat flour. This flour is produced from durum wheat and is the flour of choice when making pasta but it can be used in bread making too. It works well in ciabatta and focaccia which is not surprising as it is an Italian grade of flour. There are other grain flours available which can be used to make your bread, such as spelt and rye flour. Spelt flour forms gluten that is more digestible than wheat flour and has a slightly nutty taste which makes great bread. Rye flour, on the other hand, makes a dense cakey loaf that is still delicious. It has this texture because the proteins only form weak gluten strands in quite small quantities. Try replacing some strong flour with rye flour to produce a lighter loaf. Nowadays gluten free bread is more widely available for those who suffer from wheat intolerance. It tends to be a blend of rice, potato and tapioca. They also tend to have a gluten substitute added such as xanthan gum. Yeast is the next ingredient. Yeasts are living micro-organisms. They belong to the genus Saccaromyces – this literally means “sugar fungus.” They obtain energy by breaking down carbohydrates and as they respire they produce carbon dioxide gas. When you add water to flour and yeast, the yeast starts to convert starch into sugars. As they do so they release carbon dioxide and alcohol. The carbon dioxide forms bubbles of gas which get trapped by the gluten mesh and this causes the dough to expand or “rise.” The yeasts reproduce at a prolific rate which in turn means more carbon dioxide and more rising. All this activity also raises the temperature of the dough. This process is known as fermentation and the longer bread is left to ferment the better. There are two types of yeast available to the aspiring baker. The first is fresh yeast. If you do use fresh yeast, only buy a little at a time as it will only keep for around two weeks. Because of this I tend to stick with the second type of yeast, namely dried yeast. Dried yeast has a long shelf life, but don’t use it past its use-by date as it will have become less active. Most dried yeasts are powders and I tend to use the ones labelled as fast-action or quick yeast. Salt is the next ingredient. Salt in itself is not an essential ingredient but it does help to tighten the gluten mesh, thus increasing stability and the efficiency in how it traps bubbles of gas. This means your dough will rise higher. One word of caution: if using fresh yeast, keep it away from salt as it will kill the yeast cells. Add them one at a time and mix it into the flour so the effect will be diluted as they are blended in. As you probably know, salt is also a well-known preservative, so salted bread will generally keep for longer. Always use finely ground salt – table salt is fine (and cheap). Water is the final ingredient. Tap water is fine but it needs to be warm to help increase the activity of the yeast. The temperature should be around 30-40 o C. It must NOT be hot water, as anything above 60 o C will kill the yeast. Some people
