Try making sourdough bread

Making sourdough bread in the home kitchen can give the home baker a newfound respect for the job of running a bakery. Whole wheat bread is not something that can simply be made in an instant. It requires a starter, which is live wild yeast that has been nurtured and allowed to grow for a few days before being ready to use. But once a starter is available, bread can be made at any time!

It is happier to collect one from a friend who is willing to pass it on. However, if no one nearby has someone to start, you can make it with whole grain flour, water, and a masonry jar, then feed it every day with organic bread flour. This will initiate the necessary fermentation for sourdough bread.

Some people may find the process a bit tedious, while others find it really enjoyable. You can surf web to find any instructions. Appetizers can also be made from apricot apples, which are especially delicious for making recipes like apple cinnamon sourdough bread.

Once the starter is ready, making the actual bread isn't too difficult and requires just a bit of stirring, kneading, and rising.
