Place the butter and the flour in a heat-resistant container. Microwave for 1 minute (it's fine if the butter melts). Use a whisk to mix.
Gradually add the milk as you stir it in. Lastly, add the consommé granules and mix.
Microwave for 3 minutes. Remove at 1 minute intervals to stir (if you're worried about it at the end, take it out every 30 seconds).
Season with salt and pepper to finish.
Story Behind this Recipe
I was wondering if there was a way to easily make white sauce, so I tested various recipes.
Step 1: Stir with a whisk after the butter has melted. This is the trick in preventing lumps! Step 3: The cooking time will vary depending on the microwave, so when you take it out to stir, check on the condition as well. Once it reaches the thickness that you want, it's done.
