substitute bread flour for all purpose flour?

If you use bread flour, you might need more water. Since bread flour has a higher gluten content, it will need more liquid.

You can substitute bread flour for all purpose 1:1 in a pinch. You’ll probably get more rise and the bread will be chewier, but it’ll be edible and delicious. I usually substitute 25% (120g) whole wheat bread flour and it comes out great.
