A'ville is ~ 2,100 elevation; "just outside, say 20 mins away...", could be lower, or much higher in elevation. My wife is a helluva baker/cook, and does some adjustments on some items, as we are at 5,000 ft. For almost all recipes, there is very little to adjust
below 3,500 and esp below 3,000 ft, in her opin.
