Sweet Potato Soup

This is one of six plates I would serve if asked to make a 6-course meal or string of small plates/tapas based on Zimbabwean cuisine. I used ingredients that are commonly eaten or are considered a cornerstone of our cooking, but with a modern twist. 

The sweet potato. I've used it many times in several recipes on this website. It's one of the most widely-eaten starchy tubers in Zimbabwe so I had to use it.

There is nothing better than a thick, rich, flavourful soup and it’s not hard to achieve at all. No need to go to a restaurant for it! It’s all about the right combination of spices, rich broth, and a solid base. 

If I had more time and patience, I may have made my own homemade broth for it! Homemade is usually best.

Since sweet potatoes are starchy, they lend themselves well to soups and help thicken everything up. In this case, so does the tomato paste. It’s used in French cooking technique known as pincage which you add to mirepoix (a combination of celery, onion and carrots) which makes for a great soup base because of the flavour it adds. 

I also add the tomato paste because tomatoes are almost always present in the typical Zimbabwean kitchen and all over the markets year-round. They are also the base for most stews whether vegetarian or meat-based, it’s rare to find any Zimbabwean stew that has no tomato present. I also think it adds a flavour dimension that makes soup have more depth of flavor.

Ingredients

1 large sweet potato

1 cup mirepoix (2 parts diced onion, 1 part celery, 1 part carrot)

2-3 bay leaves

1 tablespoon hot Madras curry powder

1 teaspoon fenugreek powder

1 teaspoon cinnamon

1 teaspoon cumin

1 teaspoon coriander

1 tablespoon black pepper

1 teaspoon salt

1 teaspoon smoked paprika

2 tablespoons hot mango chutney

1 tablespoon fresh sage, chopped

1 (6-oz) can tomato paste

2 bouillon cubes

3-4 cups water

1 tablespoon butter

2 tablespoons olive oil

1 tablespoon minced garlic

Instructions

Peel and dice the sweet potato. In a large pot, heat the butter and oil with the garlic until fragrant, about 2 minutes.

Add all the spices and the sage, cook for another 2-3 minutes. 

Mix in the mirepoix and chutney until evenly coated and cook until the vegetables begin to soften. 

Add in the tomato paste and stir frequently to form a pincage - cook for another 2-3 minutes until it begins to brown. 

Pour in the water and reduce the heat to simmer. Add the bay leaves and cover with a lid for about 30 minutes or until the sweet potato softens. You'll want to regularly check your soup and stir occasionally. The soup will be thick and flagrant, add a little bit more water if necessary.

Set aside and cool the soup down. Once cooled, take out a few whole sweet potato cubes. Pour the soup into a blender or use a hand blender to puree the soup until smooth or your desired texture.

Garnish with croutons, fresh sage, and sweet potato cubes you set aside. Serves 3-4.
