In a small pan, lightly toast the coriander seeds, sesame seeds, and fennel seeds over medium heat until fragrant, stirring often.
Add toasted seeds to a food processor, along with cumin, smoked parprika, sea salt, roughly chopped cilantro, parsley, arugula, mint, scallions, serrano peppers, garlic cloves, lemon juice, and olive oil. Blend until smooth.
Garnish with roasted pine nuts and Aleppo pepper flakes, and enjoy!
Notes
This should yield a thick green harissa paste. You can add more olive oil and lemon juice if you want it to have more of a sauce-like texture.
Store green harissa paste in an airtight container in the refrigerator for up to 5-7 days.
You can top the harissa with a thin layer of olive oil o preserve freshness before storing.
You can freeze green harissa sauce for up to 3 months. I recommend freezing it in ice cube trays so you can thaw individual portions as needed and reduce waste.
