In a large pot, add broth, butter, cumin, coriander, salt, turmeric, cinnamon, ancho chili pepper, smoked paprika and bring to a boil.
Once boiling, turn off the heat and add the couscous. Cover the pot and let it stand for 5 minutes or read the cooking instructions on the product packaging.
While that is sitting, toast the pine nuts. Put the pine nuts in a small pan and cook over low-medium heat for about 2 minutes, be sure to keep shaking the pan to prevent them from burning.
Transfer the couscous to a large bowl. Add the pine nuts and currants to the couscous and stir to combine everything. Season with additional salt and/or black pepper if needed.
Serve with chopped mint.
