Heat oil in a large saucepan over medium-high heat. Add onion and cook, stirring occasionally, until soft and translucent, about 5 minutes. Add garlic and cook, stirring, for 30 seconds. Add the carrots, orange zest, broth, ginger, and bay leaf. Bring to a boil, cover pot, reduce heat, and simmer for 30 minutes or until the carrots are soft. Remove the bay leaf.
Blend the mixture until smooth. Add the orange juice and blend again. Taste and add salt and pepper, as needed. Let cool to 86 degrees, then stir in the liquid calcium.
Garnish with yogurt and pumpkin seeds, if desired.
