Sweet Potato Coconut Bisque

Okay. So if you were on my moot court team, you would find bisque funny. But you aren't, so I'm not gonna bother. This came out a little thin this time, but its pretty good. It's based off of this recipe. I sorta halved it - using only one sad potato that we had left and a half an onion.
Ingredients:
4-5 sweet potatoes, peeled and diced
1 tsp. salt
2 Tbsp. Extra Virgin Olive Oil
1 sweet yellow onion, diced
1 clove garlic, minced
1/2 tsp. cinnamon
2 c. broth
1 (15 oz.) can Coconut Milk
1 1/2 c. Milk
salt and pepper to taste
Procedure:
1. Saute onion and garlic in frying pan. Add to slow cooker stoneware.
2. Add sweet potatoes to stoneware.
3. Pour in broth.
4. Cook for 6 hours.
5. Use immersion blender to blend sweet potatoes and onions.
6. Add coconut milk and milk. Cook for another hour or two.
