Query: disappointing

With such great reviews and such a great reputation, I tried the very tempting cover recipe Devil's Food Cake. I followed the recipe with precision, sifting, weighing, mixing and the cake was just average. I used my precious Droste cocoa powder and the overall flavour was just mediocre. It didn't have an intense chocolate flavour you'd expect based on the picture (but that could be just my own expectations).I also tried the cocoa genoise and was very disappointed with that too. I found the mixing times were off - she indicated mixing for 3-4 minutes for the eggs to triple in vollume but it actually took double that.The book did provide some insight to the science of baking, describing each ingredient and their purpose, the lackluster cakes proves to be a disappointment so far.
