I’ve recently started making bread, at the moment still with fresh or bakers yeast and planning to grow my own sourdough.
It’s not very niche, but as a hobby it’s pretty fulfilling. It allows for a lot of play, and you end with something tasty. Also, makes for a great small gift for friends and family.
I make most of my bread with sourdough. It is really easy, it takes a bit longer, but there are less steps - just mix some more flour/water (sometimes salt, but I've not had a problem when I forget though others say it helps the taste to add salt - YMMV) into your starter and wait. Yeast is faster by a lot, but it is a lot more complex and so I don't find it worth it.
My wife got a square cast iron dutch oven that she bakes bread in. The breads have this nice crust and soft texture inside. To die for.
