Question: Which type of flowering plant is commonly used as a spice in Middle Eastern cuisine, Sumac or Gentianopsis?
Context: Sumac (Assyrian Neo-Aramaic: ܣܘܼܡܵܩܵܐ‎ "summāqāʾ" ("red, red shift, turning red"), Arabic: سمّاق‎ ‎ "summāq"; , or ; also spelled sumach, sumaq) is any one of about 35 species of flowering plants in the genus Rhus and related genera, in the family Anacardiaceae.  The dried and powdered fruits are used as a spice in Middle Eastern cuisine.  Sumacs grow in subtropical and temperate regions throughout the world, especially in East Asia, Africa and North America. Peanut sauce, satay sauce, bumbu kacang, sambal kacang, or pecel is a sauce made from ground roasted or fried peanuts, widely used in the cuisines of Indonesia, Malaysia, Thailand, Vietnam, China, Suriname and Africa.  It is also used, to a lesser extent, in European (particularly Dutch) and Middle Eastern cuisine.  It is also used in Filipino cuisine but rarely. Gentianopsis is a genus of flowering plants in the gentian family known commonly as fringed gentians.  These are similar to the gentians of genus "Gentiana".  Most have flowers which are blue to purple in color.  They may be annual or perennial.  They are native to Eurasia and temperate North America. Bahārāt (Arabic: بَهَارَات‎ ‎ ) is a spice mixture or blend used in Middle Eastern cuisine.  "Bahārāt" is the Arabic word for 'spices' (the plural form of "bahār" 'spice').  The mixture of finely ground spices is often used to season lamb, fish, chicken, beef, and soups and may be used as a condiment. The Orange blossom is the fragrant flower of the "Citrus sinensis" (orange tree).  It is used in perfume making, has been written about as an aphrodisiac and is the state flower of Florida.  It is traditionally associated with good fortune and has been popular in bridal bouquets and head wreaths for weddings. Orange blossom essence is an important component in the making of perfume.  The petals of orange blossom can also be made into the delicately scented orange flower water (as an alternative to rose water), a common part of both French cuisine and Middle Eastern cuisine (most often as an ingredient in desserts and baked goods). Middle-Eastern cuisine is the cuisine of the various countries and peoples of the Middle East.  The cuisine of the region is diverse while having a degree of homogeneity.  It includes Arab cuisine, Iranian/Persian cuisine, Israeli cuisine/Jewish cuisine, Assyrian cuisine, Armenian cuisine, Kurdish cuisine, Greek cuisine/Cypriot cuisine, Bosnian cuisine, Azerbaijani cuisine, and Turkish cuisine.  Some commonly used ingredients include olives and olive oil, pitas, honey, sesame seeds, dates, sumac, chickpeas, mint, rice, and parsley.  Some popular dishes include Kebabs, Dolma, Baklava, Doogh, and Doner Kebab (similar to Shawarma). Rhus copallinum ("Rhus copallina" is also used but, this is not consistent with the rules of the International Association for Plant Taxonomy), the winged sumac, shining sumac, dwarf sumac or flameleaf sumac, is a species of flowering plant in the cashew family (Anacardiaceae) that is native to eastern North America.  It is a deciduous tree growing to 3.5 - tall and an equal spread with a rounded crown.  A 5-year-old sapling will stand about 2.5 m . Za'atar (Arabic: زَعْتَر‎ ‎ , ] ) is a generic name for a family of related Middle Eastern herbs from the genera "Origanum" (oregano), "Calamintha" (basil thyme), "Thymus" (typically "Thymus vulgaris", i.e., thyme), and "Satureja" (savory).  The name "za'atar" alone most properly applies to "Origanum syriacum", considered in biblical scholarship to be the hyssop (Hebrew: אזוב‎ ‎ ] ) of the Hebrew Bible.  It is also the name for a condiment made from the dried herb(s), mixed with sesame seeds, dried sumac, and often salt, as well as other spices. Used in Levantine cuisine, both the herb and spice mixture are popular throughout the Middle East. Lebanese cuisine (Arabic: المطبخ اللبناني‎ ‎ ) (French: cuisine libanaise ) is a Middle Eastern cuisine.  It includes an abundance of whole grains, fruits, vegetables, starches, fresh fish and seafood; animal fats are consumed sparingly.  Poultry is eaten more often than red meat.  When red meat is eaten it is usually lamb on the coast, and goat meat in the mountain regions.  It also includes copious amounts of garlic and olive oil, often seasoned by lemon juice.  Also, there is a large amount of chickpeas in their diet.  Olive oil, herbs, garlic and lemon are typical flavors found in the Lebanese diet. Habib's is a Brazilian fast food company that specialises in Middle Eastern cuisine.  It has more than 475 outlets (many of them self-owned) across the country and has recently begun expansion into foreign markets.  It is known for very low prices and exotic dishes.  Middle Eastern dishes are very popular in Brazil ever since the immigration of people from that area (particularly Lebanon and Syria) into Brazil, despite their numbers being less than 0.48% of the overall population.
