Gently open the flowers by making a thin tear or cut from the tip to close to the base then peel back the two sides to make a larger opening.
Twist and peel out the anther or a stigma inside the flower at the stem end, along with any pollen that may be there so that the flower is now completely hollow. Be very careful with the pollen, it is a deep yellow and will stain anything it comes in contact with.
Add in a large spoonful of hummus (around 2 tablespoons per flower) and use the spoon to spread it from the base to around a ¼ to ½ inch near the tip. Fold the sides near the opening back in. They can be completely rejoined or left slightly open so that the filling is visible.
