Combine the olive oil and onion in a Dutch oven or heavy pot over medium-high heat. Sprinkle with 1/2 teaspoon salt and cook, stirring, 10 minutes, until just starting to caramelize. Add the garlic and ginger and cook, stirring, 2 more minutes, being careful not to burn the mixture. Stir in the carrots, potato and the chicken or vegetable stock. Bring to a simmer, cover and cook until the carrots and potato are very tender, 15 to 18 minutes. Keep warm. Meanwhile, in a small saute pan over high heat, lightly toast the pine nuts. Set aside to cool. In a small bowl, combine the yogurt, honey, thyme and 1/2 teaspoon pepper. Puree the soup with an immersion blender until very smooth (or puree in a regular blender in batches). Adjust the seasoning with salt and pepper and serve with a dollop of the yogurt mixture and some pine nuts.

When blending hot liquid, first let it cool for five minutes or so, then transfer it to a blender, filling only halfway. Put the lid on, leaving one corner open. Cover the lid with a kitchen towel to catch splatters, and pulse until smooth.
