This is a distillation of several recipes, this is how we like it.

Ingredients for two people
10 oz fillet beef
1 tbsp finely chopped shallots
1 tbsp chopped capers
1 tbsp chopped gherkins
1 teasp dijon mustard
1 teasp tomato ketchup
1/2 teasp worcester sauce
1 tbsp olive oil
Ground pepper & quarter teasp salt
1 egg yolk (please excuse the picture)

Method
Chop fillet in a food processor, be careful, not too fine. Mix everything together and press into a food ring to give a nice shape although it’s not essential.

Serving recommendation.
Of course, serve it with chips, salad if you must!
