Around the World in 30 Soups: This month we’re collaborating with chefs, cookbook authors, and our own Kitchn crew to share a globetrotting adventure in soups from countries and cuisines around the world. Today’s stop: Tanzania.

For a window into Tanzania and its soups we turned to Evi Aki of Ev’s Eats and author of Flavors of Africa. Like so many soups from this part of the African continent, it leans on the richness and flavor of coconut.

Supu Viazi, or coconut potato soup, is a simple dish that screams the flavors of Tanzania. It’s packed with some of my favorite ingredients (like coconut milk and potatoes) and it’s why I love it so much. It has an underlying taste of coconut that doesn’t leave the soup tasting sweet, just deliciously velvety.

Soups in Tanzania are often thickened with coconut milk — since there’s an abundance of coconut trees on the coastline. You’ll find that coconuts, whether it be the flesh or the milk, are used a lot in Tanzanian cuisine. One bite of this soup instantly transports me to a tropical state of mind.

The base of the soup starts with peppers, onions, and tomatoes — a trio that is quite common in African cooking. The potatoes and green banana add some starch and are quite filling since this soup lacks any meat. Finished off with some sliced avocado on top, this soup is delicious and brings me so much comfort. You can serve this as a meal on its own or as a starter before any other meal. While the ingredients may be simple, there is nothing simple about the taste.
