For the most part, countries that border each other tend to use similar food ingredients in their cuisines. Still, there are some unique pairs of countries that border each other, but have extremely different food. One possible answer was developed by analyzing the data from the Country Food Similarity Index. According to the data, Chad and Libya are the nations with the least similar food that border each other.


CHAD-LIBYA
At first glance, Chad and Libya seem likely to share culinary similarities. These two nations share a lengthy border in northern Africa, but they are separated by the vast Sahara Desert. Both countries are predominately Muslim. Their food ingredients are extremely different due to history, ethnicity, and affluence.
Libya’s cuisine is heavily influenced by its Arab identity and proximity to the Mediterranean Sea. Wheat-based staples such as couscous, bread, and pasta are common in Libya. In contrast, Chad relies heavily on millet, sorghum, and corn as staple grains, especially in rural regions. Chicken and saltwater fish are the two most common sources of protein found in Libya. In contrast, beef and lamb are the most popular meats in Chad. In addition, Chad tends to use a lot of peanuts, leafy greens, and locally sourced ingredients like okra. Onions and tomatoes are more common in Libyan food.
