i use [this](https://www.kingarthurbaking.com/recipes/sourdough-bagels-recipe) recipe by king arthur. i followed every step to a t.

usually i can figure out what i've done wrong to mess up a recipe, but for the life of me can't figure out what i'm doing wrong with these bagels. i've made them four times and they've all turned out with these gummy spots. i think the only thing that has varied from each one is how long the bulk rise/resting period is.

please help me out!
