  • 5 sticks (20 ounces) room temperature unsalted butter, cut unto 1 tablespoon pieces

Preparation Instructions
  1. TO MAKE THE CUPCAKES
  2. Preheat your oven to 350˚ (for high altitude 310˚).
  3. Place cupcake papers in two cupcake pans and set aside.
  4. In the bowl of an electric mixer fitted with the whisk attachment, whip the egg whites and cream of tarter on high until stiff peaks form.
  5. Lower the speed to about medium and sprinkle the sugar over the top.
  6. Add the zest and juice.
  7. Remove the bowl from the mixer and fold the flour and powdered sugar in.
  8. Scoop the batter into the cupcake trays, they really don't puff up like normal cupcakes so go ahead and fill the cups.
  9. Bake until the tops are a nice golden brown, about 25 minutes (high altitude about 35).
  10. Remove from oven and cool completely before frosting.
    TO MAKE THE BUTTERCREAM
  11. Place the bowl of an electric mixer over a pot of boiling water.
  12. Add the eggs and sugar and whisk until the mixture is hot and the sugar is dissolved. Yes, stick your fingers in there and rub them together to see if the sugar is dissolved.
  13. Place the bowl on the mixer and beat the mixture on high until it is thick, about 5 -10 minutes.
  14. Lower the speed to medium and add the butter a little at a time until it is all in there and smooth.
  15. Add the vanilla and the jam.
  16. Beat until thick and smooth.
  17. If it seems like it isn't coming together, try adding a little more butter. It should come smooth.
  18. Pipe onto cupcakes and top with a little mint and a blackberry to serve.
