In Georgia, economists measure the well-being of citizens by using the most popular Georgian food, the Khachapuri. They call it the Khachapuri index. The Khachapuri index requires the ingredients that are needed to cook one khachapuri: 250 g of flour, 100 g of cheese, 50 g of yeast, 75 ml of milk, 1 egg, and butter (vegetable and cream), sugar, and salt. The use of gas and electricity is also included in the price. In 2019, the Khachapuri index reached a historic high due to a 12% fall in the exchange rate of the lari (the currency of Georgia) and an increase in food prices.
