Whipping the Egg Whites:Be sure that your bowl and beaters are super clean, as any fat present will keep you from whipping them into stiff peaks. Allowing the eggs to come to room temperature will also make this process easier.
To toast the pecans, preheat the oven to 350°F/180°C, spread pecan halves on a small quarter-size sheet pan, and toast for 6-8 minutes. Be careful not to burn them!
To Store:Keep this cake in the fridge, in an airtight container for up to 4 days.
