There are many cultured milk products, kefir and cheese among them, but yogurt-type dishes are characterized by a gelatinous texture, and a fairly limited number of bacteria strains, usually between two and six. Yogurt is also something that can be made fairly quickly.
Many cultures have traditional cultured milk dishes based on yogurt or yogurt-like cultured milks. Additionally, there are a variety of traditional yogurts from different parts of the world.

Chaas is similar to lassi, but has more water and less butterfat. Seasonings include salt, coriander, ginger, and green chilis.
Clabber is a naturally fermented milk, made by letting raw milk sit at room temperature for several days. The bacteria present in the milk acts much like yogurt bacteria, but more slowly, to produce a thick, slightly sour product similar to yogurt but without yogurt’s characteristic astringent flavor.

Amasi (maas in Afrikaans) is an African yogurt with a mild, almost cheesy flavor. It’s made by allowing raw milk to ferment naturally in a calabash (squash) container or a container made from hide. It can also be produced very much like yogurt, with Lactococcus lactis subsp lactis and L. lactis subsp cremoris bacteria in pasteurized milk.
Dadiah/Dadih, from Indonesia, is made by letting unpasteurized buffalo milk ferment at room temperature in a bamboo tube capped by a banana leaf.
