There are lots of variations on this epic sandwich, which is famous throughout NYC delis. This is our take on the Reuben salt beef sandwich. Note: the salt beef can be swapped out for our ready prepared English Corned beef.
Method
Make the relish by simply stirring together the mayo, ketchup,
mustard, horseradish and a few drops of Worcestershire sauce and
keep to one side
Next make the cheese sauce by melting the butter and flour
together over a medium heat, then gradually whisk in the milk to
create a thick white sauce followed by the cheese. Season to taste
and keep warm.
To assemble:
Shallow fry the bread in melted butter until golden.
Spoon the sauerkraut between two slices of fried bread,
followed by the salt beef, top with the cheese sauce, then finally
a dollop of the relish. Sandwich together and eat straight away
with sliced gherkin.
