How exactly are you going to prepare them? Spread the mustard on the beef, add a slice of cornichon and some hacked onion, roll the beef and tie the roll with a slice of bacon?
Almost.
Salt & pepper the beef, thinly spread the mustard over it, but 1-2 sclices of bacon on it (usually I take pieces of bacon, not slices). Then roll up the beef.
Sear it well from all sides in a pot with a quatered onion and some tomato paste. Pur meat broth into the pot until the
Rouladen are half covered, add some pimento and a small dried bay leaf.
Let it simmer gently for 1-1.5 hours.
I will serve it with some very young needle beans wrapped in bacon and potatoes.
