It’s that time of year for Asparagus to start popping up and one of my favorites in Asparagus on Toast. Your classic white sauce with fish, and some of your favorite bread toasted. I always add the rue element to any gravy or sauces. Browning the flour always gives it a nutty flavor rather than just having that raw flour taste. In this dish just turn the rue to a light yellow. No matter what you're using for fat, butter, olive oil, etc. it takes one part fat to one part flour
