Heat a medium-sized pot on medium-high. When the pan is hot, add the oil. When the oil gets hot, add the carrot slices, onion slices, and cumin.
Sweat the carrots until they start to soften on the edges.
Add the carrot juice or chicken stock and simmer uncovered for about 20 minutes or until the liquid in the pot reduces by a third.
We used a hand blender to puree the carrots, which worked well, but you could also transfer the ingredients to a blender or food processor and process until smooth.
Taste and adjust seasonings with salt and pepper.
Serve as a side dish to whatever you're cooking.
