When using plain flour to make bread in a machine how much dried yeast should you use?

For every 500g of plain flour, the amount of dried yeast you should use will vary depending on the type of bread you are making and the desired texture of the dough. Here are some general guidelines:

1. For a basic white or brown loaf: around 1-1.5 teaspoons (5-7g) of dried yeast.

2. For a richer bread, such as brioche or challah: around 1.5-2 teaspoons (7-10g) of dried yeast.

3. For a sourdough loaf: you will need to use a sourdough starter instead of dried yeast.

It's important to check the packaging of your dried yeast for specific instructions and measurements, as different brands and types of yeast may have varying strengths and require different amounts. Additionally, the environment and temperature in your kitchen can also affect the rising of the dough, so it's a good idea to keep the area warm and draft-free while the dough is rising.
