Place the minced beef into a large mixing bowl and combine with the chopped gherkins, capers and the chopped parsley.
Now add the shallots and pour in the lemon juice, olive oil, mustard, Worcester sauce, mayo and a few drops of Tabasco sauce to your liking. Season with salt and pepper to your liking and combine everything thoroughly.
You can add the egg yolk in at this point or reserve them to garnish the tartare at the end. It's up to you!
Taste the tartare and adjust to your preference.
Divide the beef tartare into 2 plates and place them in the fridge to chill before serving.
When ready to serve, sprinkle a little bit of salt and freshly ground black pepper and top them with one egg yolk each and a touch of chopped parsley.
