Can I use bread flour instead of AP for all or part of this?

Hi Olivia! I'll admit I'm not a bread expert, but I believe you can make a 1:1 substitute with bread flour for AP flour. The results may be slightly different, but I think it should work! Here's a guide I found, which has a section on substitutions. https://www.realsimple.com/food-recipes/cooking-tips-techniques/baking/difference-between-flours I hope that helps!

Hey Olivia—yes, I imagine that would work just fine!
