I made lemon pound cake again, but this time I decreased the baking powder and sugar and increased the flour. Instead of a valley of cake, we have a lovely hill. I was concentrating so much on the high altitude adjustments that I forgot to think about the lemon. I got the lemon zest in though, but lost the opportunity somewhere along the line to put in some lemon juice. Oh well. It's still pretty yummy, or so says Isaac.
