That's funny niquejim. I made garlic soup for the first time tonight too.
I used this recipe: Cream of Garlic Soup
I used mostly chicken stock, with some vegi stock. I added a 1/4 tsp of salt. I cooked the flour for a while before adding the milk and stock.
It was really good. Next time I will use a wooden spoon instead of a whisk. I will also add the flour much sooner than the recipe says, to cook the flour properly without risking over cooking the garlic. I don't want to risk a raw flour taste.
