Shatta (Arabic: شطة "shaṭṭah") is a popular hot sauce made from wholly grounded fresh chili peppers by mixing them with oil (usually olive). Vinegar, garlic, or other spices are commonly added. There are two varieties of Shatta: green and red. The red variety is made with tomatoes. It is made from piri piri, or similarly hot peppers. The degree of hotness varies according to the type of chili used and preference of the maker (homemade Shatta is usually hotter than commercial brands). Commonly used in falafel sandwiches, hummus dishes, or as a condiment. Muhammara ( "muḥammarah") is a hot pepper dip made from Aleppo pepper, ground walnuts, dried bread, and olive oil. Other spices and flavorings may be added. It is served as a dip or spread for bread or as a sauce for fish and meat. The dish is also known in Turkey, where it may be called "acuka".
