Next, in a medium sized
saucepan melt 1/2 cup butter or
ghee. Sauté chopped onion and garlic. Whisk in
Arrowroot Flour. Add cream and keep stirring as it thickens. (Note: a reader, Lisa, said in the comments that it was a little too heavy with so much cream, so you might try less cream and more milk or chicken stock if you want it a little less creamy.) Add
chicken stock, slowly, keep stirring as it thickens back up. This will take a few minutes. Add
sea salt and pepper to taste. We like a lot. Stir in 1/2 cup of shredded Parmesan cheese.
