A classic winter soup, this version has deep flavour and layers of spice that proffer subtle heat. A few spoonfuls of store-bought harissa are the secret to subtle warmth tempered by warm cinnamon and cumin. A finishing touch of lime yogurt gives a fresh and zingy flavour that will have you coming back for more.
Harissa is a spicy chili paste from North Africa. It typically contains chili peppers, olive oil, lemon, tomatoes, and spices like cumin and coriander.
In large saucepan, sauté onion and garlic in olive oil on medium heat for about 3 minutes, or until onions appear translucent. Add squash and sauté for a further 5 minutes. Add cinnamon, cumin, coriander, and salt and sauté for another minute before adding harissa. Stir frequently over next 2 minutes. Raise heat to high and add vegetable broth, stirring well. Bring to a boil, then reduce heat to gentle simmer and allow to cook for approximately 20 minutes, until squash is tender. Remove from heat and allow to cool slightly. Using hand mixer, blend soup into a fine purée.
Combine yogurt, lime zest, and 2 Tbsp (30 mL) lime juice. Add remaining 1 Tbsp (15 mL) lime juice to soup.
Ladle soup into bowls and serve with a dollop of lime yogurt.
