Finely grind the sunflower seeds in a blender. Then gradually add the other ingredients and continue to mix until you have a spreadable mixture. If the mass is too firm, you can add orange juice until the desired consistency is achieved.
With anise, mustard seeds, orange peel and / or fresh mint you can vary depending on your preferences.
For example, I like the spread with ground anise and freshly chopped red peppermint leaves. The amount of syrup can of course be adjusted to suit your own taste.
