I created this, this afternoon.
I'm guessing the proportions.

1 sweet potato
2 tsp ground cumin
1/2 tsp ground coriander seed
1 tablespoon butter
little salt and freshly ground pepper
1/3 cup of "fresh" coconut milk (from a can)
1/2 tsp lemon zest

Cook potato 4 mins in microwave. Peel, slice and put in sauce pan.
Over low heat, add butter and about 1/4 to 1/2 cup water. Mush around.
When pasty, add spices and coconut milk. Cook ten minutes on low.
Remove and blend. Wow! Eat.

Recipe is for one human.

Here's just a nice picture to look at. Enjoy.
