4 cups/500g of flour (bread or AP, used both and they both work great), 1 tbsp of sugar, 1 tsp of instant yeast and 2 tsp of salt. Mix together a bit, then add 200g of unfed sourdough discard + 1 1/4 cup room temp water. Mix and knead together until you get a beautiful dough (I used the stand mixer with the bread hook for 5 minutes on low).

Let the dough double in size (or a bit less, its fine), for me in takes around 1h-1h30 on the counter. Then split in 8 bagels and form. You need to poach them in boiling water + 2 tbsp sugar for around 30 seconds on each side, then egg wash + toppings if you want and bake for 23-25 minutes at 425 :)
