You can make muhammara with seeds instead. I recommend hemp seeds. You can also try sunflower seeds. Some toasted pine nuts give a lovely piquant taste. A variety of seeds also works great. Replace the 1 cup of walnuts with 1/2 cup sunflower seeds and 1/2 cup hemp seeds. Other seeds you can u0022play aroundu0022 with are pumpkin seeds and sesame seeds. Pumpkin seeds have a powerful flavor, so I would not use the whole amount of those. If you use green pumpkin seeds, you get a brown paste, so it might not look so delicious.
