Bread Improver
Some ingredients help bread doughs rise faster and higher, help the bread keep longer, taste better etc. We use a bread improver, based on soy flour, which contains Vitamin C and enzymes. It is technically not essential to breadmaking but does noticeably enhance the lightness, taste and keeping qualities.
Salt
Bread made without salt is often dry and crumbly, but is always bland and tasteless. Not only does the salt bring out the flavour in your bread, it controls the action of the yeast as well and allows the gluten to mature properly. Too much salt will kill the yeast, but too little will let the yeast grow too fast and the bread can have a sour, yeasty flavour and the gluten structure will be poor.
Sugar
There is no real need to include sugar in your bread, it will make your bread rise a little faster and be a little lighter in texture. You can substitute honey, malt or golden syrup for the sugar, just dissolve in the water and include as part of the liquid measurement.
