Bread
A while back I became a little obsessed with making bread. To me its kind of like magic. Flour, yeast and water combine to make this crazy thing. I also like anything that you can always be better at. Making bread is something very satisfying, the physical aspect of kneading by hand, creating something out of basically nothing. A bag of flour is $5 no matter what the size. You can buy 5lbs, 25lbs or 50lbs for basically the same amount of money.
If after looking at this you are thinking, “I should start making bread.” You are a 100% correct. You should. Start here.
