Sweet sweet potato soup

Thanks to the farmer's market this past weekend, we had lovely soup, which was awesome on this rainy rainy evening.

2 sweet potatoes, quartered & baked
1 apple, cored, peeled and baked
garlic cloves, peeled and roasted
olive oil
onion
celery
carrots
lemon
garam masala
cumin
vegetable broth

Roast potatoes, apple, and garlic at 400 degrees for about 20 minutes. Allow potatoes to cool & remove skins. Simmer veg broth, onions, olive oil, celery, and carrots in a big pot. Blend potatoes, apple, garlic, and a bit of broth in a food processor. Add to soup pot. Add spices. Bring to boil. Add lemon zest. Add sprig of mint for garnish.
