Rye flour vs Whole wheat flour
Both are whole grains, but rye has very little gluten, so it makes denser, moister loaves with a distinct tang. Whole wheat has more gluten and a milder, nuttier flavor. Swap rye for up to about a third of the whole wheat to add depth without losing too much structure. Go heavier and the loaf turns dense and sticky, which is the point in a pumpernickel but not in a sandwich loaf.
