Sweet Potato and Apple Soup

Recipes calls for two "medium" sweet potatoes. Considering the sweet potatoes in my area range from 0.5 to 3 pounds, that was a bit vague. The notes suggest you can substitute with 4 cups of chopped butternut squash, so I did 4 cups of chopped sweet potato. While chopping my three apples, I realized I would have more chopped apples than sweet potatoes, so I left out 1/4 of the apples to keep it from being too sweet and added in a little more sweet potato to replace it. In the end it was still a touch too sweet, and thinner consistency than the photo. However, the flavour was really good so next time I will do 1/2 the apples and replace the missing quantity with sweet potatoes. Also, I'll double the ginger for added warmth.
