I invented cardamom sugar. I made a dish that called for simmering and then steeping crushed cardamom pods in half and half and then straining them out. I couldn't bear to just throw out the seeds (which had separated from the pods), so I decided to grind them. But there weren't enough to grind well, so I decided to add some sugar and grind them together. Voila! Cardamom sugar. It smells heavenly!
Then I went looking for something to do with it. I had egg whites leftover from the same recipe, so I decided to make meringues. I found a recipe for spicy walnut meringues that called for cinnamon and then rolling the meringue in sugar before baking. I used cardamom instead of cinnamon, and then used the cardamom sugar (mixed with plain sugar) for the exterior. Delicious!
