Step 1: Melt butter in a skillet or dutch oven on medium-low heat and add crushed garlic. Cook about 1-2 minutes before garlic burns and butter browns. Add flour and mix until flour is mixed in to create a roux. Allow the flour to cook for about 3 minutes on medium heat. Add salt and pepper. Add in the milk and mix. Allow the milk to simmer until it begins to bubble and thicken.
