Make the filling

1. Whip the cream till soft peaks form. Fold in the sugar, cardamom & cocoa. Give it another quick whip till the cocoa is well blended. Discard the cardamom skin and refrigerate for at least an hour to get it chilled.

Make the puffs

1. Boil the water in a saucepan. Add the butter to the water and stir until melted. Stir in the flour & salt, and mix well till the dough starts to come together and a sticky, homogeneous ball is formed.
2. Remove from heat and add 1 of the eggs. Beat well and let the mixture stand for 3-5 minutes. Add the other egg and, once again, beat well. Let it stand for 10 minutes. Mix for the last time and put the mixture into a piping bag. Snip off the edge of the bag, and put dollops of the mixture on a cookie tray, approximately 2 inches apart. You may use a spoon to do this, but the dough is rather sticky so I find it easier to use a bag!
3. Pre heat the oven to 375 F and bake for 20-25 minutes, till the crust is light brown and a toothpick inserted comes out clean. Mine were done in 22 minutes.
4. Cool completely and then fill with a teaspoon of the cocoa cardamom cream. Eat immediately.
