I recommend not getting into baking your own sourdough. I started during COVID because we couldn't get bread or even yeast at the store, just 50-pound bags of bread flour online. Now I'm stuck doing the whole process every fucking week because the bread is just so much better than anything you can get at the store.
No, it's not difficult or really time-consuming at all, but it does tie me to the house for a couple of nights in a row whenever I make it, and I have shit to do. I've also started sleeping through my alarms so I've developed a tendency to over-ferment a little bit.
We can get decent bread at bakeries in the US (sometimes), but it's not like having a process that is fine-tuned to your personal tastes, and even at these places what you buy can be a couple of days old. There's nothing like fresh bread that has just barely cooled off enough to eat.
We have LiDL here, too, and although their bread is just heated-up frozen dough it's still pretty good. Better than anything prepackaged, that's for sure.
