This recipe is for S.O.S. AKA Shit on a Shingle AKA Same Old Stuff AKA "chipped beef."
2 Tbsp. butter
2 Tbsp. all-purpose flour
1 1/2 c. warm milk
1/2 jar dried beef (about 2.5 oz)
1/3 c. canned corn (or frozen, if cooked)
1 pinch cayenne pepper
Put dried beef slices in a bowl. Pour boiling water over them. Let sit briefly and drain (this removes some of the extra salt). Chop into roughly 1/2" squares.
In a medium saucepan over low heat, melt butter. Whisk in flour all at once to form a roux. Whisk in warm milk, a little at a time, increase heat to medium-high, and cook, stirring, until thickened. Stir in beef, corn, and cayenne. Heat through. Add black pepper and salt (optional) to taste.
Serve over buttered toast.
