Aha, finally a chance for me to get on my high horse.
Sourdough Bread.
It’s fine I suppose, it is not actively bad, but unless you go to a greasy spoon literally everything that is served with bread is sourdough. For one it tastes kinda, well, sour. When toasted the crusts can be utterly impenetrable with the de-rigeur butter knife. In many places, the crumb is so full of holes that the misbalance between crust and crumb is just so weird.
It’s gotten to the point where sourdough is so ubiquitous that I am convinced everyone is just slightly suffering a mass delusion that it is somehow better.
If you have a plate with buttered / toasted slices of the following are presented: Soda bread, plain fresh white bread, fresh granary bread, french baguette, plain pan loaf, even a morning roll…and sourdough. I genuinely think you are lying to yourself if you choose sourdough bread over any of those.
