After experimenting with a few different recipes...this happened! The end result was DIVINE. It's warm, thick and full of flavour, also, it's cheap to make. There aren't many ingredients that aren't already found in the household pantry.
This soup is great for the winter, and the contrasting flavours of the sweet potato and chilli are incredible! As noted above, I added other types of chilli, but that is because I am a fan of it. It's a very fragrant soup, and I guess that can be pinned to the garlic. The quantities can be altered for taste, but the main bulk (stock, potato) will serve about 4 people depending on portion size.
