Best red sauce for enchiladas

I had given up on using red sauce for my enchiladas because the store bought kind is so bitter. So a friend of mine brought me enchiladas with the best red sauce and I asked her for the recipe. I made it as well and it turned out so yummy! Now I want to make enchiladas all the time!

• 1 Tablespoon canola oil
• 1 Tablespoon flour
• 1 can of red enchilada sauce (small)
  
• 4 cups of chicken broth
• 2 Tablespoons cilantro
• salt and pepper

In a large saucepan over medium heat, add oil and flour and whisk together to make a paste, cooking for one minute. Pour in the red sauce, chicken broth, cilantro, salt and pepper. Bring to a boil. Reduce heat and simmer 30-45 minutes.
