Hey!
Recently while trying to get GPT4 to give me some clever info on how to easily make better buns I learned about Tangzhong. It’s just 1/5 flour to water in a small pot and stir until thickened and drop about half a cup into your dough. It does wonders for my very simple buns and also awesome to add to Snúðar (https://vallagrondal.is/snudar-betri-en-ur-bakariinu/) 🙂
In german you call it Brühstück. You can also just pour boiling water over old bread or flour to achieve a similar effect.
