Pre-heat the oven to 160CFan. Slice the carrots and using a little oil saute the carrots in an oven-roof saucepan. After 5 minutes cover the carrots with a little water until just level with the top of the carrots and place in the oven for an hour.
Allow the carrots to cool slightly then add all remaining ingredients to the pan and blitz together using a stick blender, season to taste. Adjust other flavourings as your see fit. Delicious served warm.
This recipe would also work well with other vegetables like butternut squash or with pulses like butter beans. You could just as easily use leftover roasted vegetables.
