Harissa is a Tunisian red chile sauce. Commonly used to marinade protein, for soups, vegetables, and even dessert at T.O.I.C..
Wikipedia says "main ingredients are piri piri (type of chili pepper), serrano peppers and other hot chili peppers and spices and herbs such as garlic paste, coriander seed, red chili powder, caraway as well as some vegetable or olive oil. It is most closely associated with Tunisia, Libya and Algeria but recently also making inroads into Morocco according to Moroccan food expert Paula Wolfert. It can also be found in countries with strong Arab presence such as France or Germany. In Israel harissa is a common topping for falafel."
I just love the flavor and recently wanted to try it as ice cream. I recommend it with Caramel Sauce & Himalayn Pink Salt on top.
