Gravy

I was around 12 years old when I visited the orthodontist to receive braces.  I remember that my dad took me to the appointment.  After a couple of hours of keeping my mouth open while my new hardware was installed, I was hungry and ready to eat.  I asked the staff, "What can I eat?"  They replied, "You can eat anything you want."  I asked my dad if we could eat at Wendy's and he obliged.  However, when I bit down into my hamburger I just burst out crying - my teeth hurt so much!  All I could do was sort of gum some fries like an old man.  It was not a happy experience, but definitely memorable.  Yesterday, my daughter, now 12, had her braces put on.  She is undergoing the same pain as her teeth re-adjust.  For dinner tonight I made mashed potatoes.  Initially, I did not make gravy, but she asked for that too.

Ingredients
2T olive oil or butter
2T flour
salt, to taste
1C broth (chicken, vegetable, or beef)

Directions
In a sauce pan over medium-high heat, heat the oil or melt the butter.  Using a wooden spoon or small wire whisk add the flour and salt to the oil/butter and mix well.  Cook for 1-2 minutes.  Pour in the broth and stir to combine with flour/oil mixture.  Make sure no clumps remain.  Keep stirring until gravy boils for approximately 1 minute.  Gravy will thicken as it cooks.
