Q. Why is it common to salt the exterior of a baked potato?
A. Chefs started doing this years ago to allow the salt to absorb or draw out the moisture of the potato while baking, which results in a dry, fluffy potato. They used to do something similar with prime rib, sometimes baking it over rock salt. Check out these recipes on our website:
