I just started getting into homemade bread. I have noticed that when I eat homemade bread versus store-bought bread I always end up with heartburn.

I mentioned it to my boyfriend and he said that he's also getting heartburn from eating the bread.

Is there anything I can tweak about my recipe to stop this weird side effect?

Currently the bread recipes I have tried are very simple. The ingredients are:

-Brear flour -Milk -Egg -Instant dry Yeast -salt -butter -honey
