In an 8-quart saucepan, heat 1 tablespoon of olive oil over medium heat. Add the coriander and cumin seeds and saute until fragrant, about 2 minutes. Add the ginger, onion, and jalapeno and sweat for 4 minutes. Add all liquid ingredients and bring to simmer. Add the carrots and simmer for 2 hours.
Remove from heat and puree using an immersion blender or regular blender. Strain twice through a fine-mesh sieve, pushing through all the solids with a rubber spatula. Chill in the refrigerator for 2 hours.
Garnish with creme fraiche and cilantro and serve.
