Cut steak into bite sized pieces and refrigerate until needed.
Heat oil in fondue pot. Oil will need to be deep enough to cover meat on fondue fork.
To make sauce, melt 1 tablespoon of butter in small saucepan and combine with flour. Stir until smooth.
Add remaining butter and continue stirring.
Add milk, capers with liquid, Worcestershire sauce, and mustard. Cook until thickened, stirring to keep smooth. Pour sauce into serving dish or dishes.
To do fondue, skewer a piece of steak with fondue fork, then set in hot oil. Cook to desired doneness and dip in mustard caper sauce.
Notes
Steak will cut more easily if partially frozen (or a good kitchen scissors works well too)Because of the cooking time, we usually use 2 fondue forks per person.This will serve 3 as an entree but 6 or more as an appetizer
