Sweetpotato soup

One of my most requested recipe is this one, and honestly it's much simpler than it looks! As a student one of the most important thing is that I want most of the meals I eat to be simple and cheap. This recipe is for one person and this is what you need:

1 small/medium sweet potato

1 dl creme fraiche 

½ cube of chicken or meat stock

some lime juice

salt

thyme

some spring onion 

water

mixer

pot

(avocado for garnish)

Start by peeling and slicing the potato into smaller pieces. Put them in a pot and fill it with water so that it just covers the potatoes and crumble half of a stock cube into the water. Put it on the stove and bring it to a boil and then let it simmer until the potato pieces turn soft. 

When the potatoes have turned soft pour them into the mixer together with 1 dl of creme fraiche and mix it until its smooth. Pour the soup back into the pot and put it on low heat. Squeeze some in lime juice and season with salt and thyme.

Slice up some spring onion and some avocado for garnish!
