I've been eating this spicy green dip/spread for as long as I can remember. It's referred to simply as "Green Stuff" in my family and my dad is always expected to bring to every single gathering. He usually makes it in two batches: so-so spicy and SO-SOOO spicy. If ever you visit my parents house and there's oddly no Green Stuff in the fridge, my dad will gladly run out to the garden, pick some fresh ingredients, and whip up a fresh batch in no time.
2 bunches of parsley (you can also use cilantro, depending on what flavor you like better)
2-4 jalapeños (or serranos if you want it even more spicy)
1 good-sized garlic clove
3/4 cup olive oil
1 cup raw walnuts
Sea salt and fresh ground pepper to taste
The easiest way to make Green Stuff is to throw all the ingredients in a food processor. Since I don't have a food processor, I have to add the ingredients systematically into my blender in order for it to blend well.
I start with one bunch of parsley, stems and all. Add the olive oil, lemon juice, one pepper and blend until fully incorporated. Once you got that going, add the second bunch of parsley and the remaining peppers one by one until you think it's spicy enough (you can remove the seeds if you want to keep the heat subtle). If you have to add more olive oil to get it to mix smoothly, so be it.
Then throw in the garlic, walnuts and salt and pepper. Blend. Scoop into some mason jars for easy access.
