Drain the meat. Reserve all sauce. There should be about a 1/2 cup or more of sauce... Save this.
Now, dredge the beef in flour; be sure to cover all pieces thoroughly. Fry the beef in the peanut oil. Don't burn the pieces, but be sure to use enough oil and heat to get them crispy. I like to use a very high heat at first and then reduce heat and toss them gently... until they are crispy brown. When done, drain on paper towels or a butchers paper.
