Moving to a small town in Utah that is at 7100 feet above sea level, figuring out how to adjust my baking recipes was trial and error; more error than success. I could get my baked goods cooked on the outside, but inside was always too gooey; letting them bake more only gave me burnt tops, bottoms and sides.
This baking book gives detailed additions depending on the altitude, not just one tablespoon or cup fits all adjustments. There are easy recipes to follow as well, so a great addition to recipes I already have.
