I decided to use fresh oregano for this recipe, so I started by stripping the leaves and flowers from the stems. The easiest way to do this is to hold the tip of the branch between your finger and thumb and then run the fingers of the other hand along the stem.
I first tried crushing the flowers with a pestle and mortar. While this was effective, it was time-consuming and required too much muscle power. I decided to chop the leaves instead, which proved much quicker but equally successful.
