How can I make lemon and chilli liquid to have with hummus? A few weeks ago I had hummus at the famous Abu-Hassan/Ali-Caravan place in Jaffa, Tel Aviv. When you order hummus there you also get a small bowl of lemony chilli liquid on the side. The liquid is hot and really bitter.


The idea is to mix the chilli liquid in with the hummus to get it as hot as you like. It's really delicious!
Does anyone have any creative ideas about how I could make this kind of liquid at home? I have dried chilli flakes, and as a first pass I can fry them in some olive oil, drain and mix in lemon juice. I wonder though if anyone created this kind of thing before and is in a position to give some advice.
Thank you!
In Israel I have often seen hummus/falafel/thina served with a hot sauce called skhug, I have mostly seen the green variety (skhug yarok), which is a sauce made of fresh herbs, garlic, chili, lemon juice, garlic, olive oil, and some spices.
Hummus is often just served with thina on the side and with olive oil, but there is a lot of variety ... I have seen sauces based on olive oil and lemon juice, similar to what you describe (although not biter ... but the bitterness could also come from blending the olive oil). But I never saw it being prepared in front of me or it being called a particular name, but it looked a little like a thin vinaigrette.
Using my extremely limited hebrew knowledge and google I found this recipe.

The ingredients translate to:

2 hot chilies
3-4 cloves of garlic
3 tbsp olive oil
juice of half a lemon
salt
additional recomendation:
1 tsp cumin
sugar
Preparation: Put all ingredients into the food processor and turn into the sauce. Taste and adjust spices/oil/lemon juice to taste. And add sugar if too sour to balance the flavor.

You can let sit a little for the flavors to combine ... and strain out remaining bits if desired.
I am not sure if this is the sauce that you had ... but it could be very similar. Anyway ... it sounds tasty.
