Herbed Roast Beef with Caper Mayonnaise

Tips: Beef fillet cooking times for medium: 20mins for a fillet 5cm in diameter or 25 mins for a fillet 7cm in diameter. The beef can be cooked up to 2 days before serving. Cool to room temperature, then wrap in foil and place in the fridge. Slice the beef and drezzle with the caper mayonnaise just before serving. The caper mayonnaise will keep for up to 5 days in an airtight container in the fridge.

1 cup		continental parsley
½ cup		oregano leaves
10		anchovies
3 cloves		garlic
¼ cup		olive oil
1.3 kg		beef fillet
Caper Mayonnaise
2		egg yolks
1½ Tbs		fresh lemon juice
1½ tsp		dijon mustard
2/3 cup		olive oil
1½ Tbs		small capers

1	Preheat the oven to 200°c. Line a large roasting pan with non-stick baking paper.
2	Process the parsley, oregano, anchovies, garlic and 2 tablespoons of the oil in a food processor until the mixture forms a rough paste. Set aside.
3	Tuck the tail end of the beef fillet under to make the fillet an even thickness all the way along. Tie with kitchen tring to secure. Take out your largest non-stick frying pan. If the fillet is too long for the pan, cut it in half. Rub the fillet all over with the remaining oil and season well with pepper. Heat the pan over high heat and sear the fillet for 2-3 mins or until browned on all sides. Transfer to a plate and spread the herb paste all over to coat.
4	Transfer the fillet to the prepared roasting pan and cook in preheated oven for 20-25 mins for medium or until cooked to your liking. Transfer to a plate, cover loosely with foil and set aside to cool.
Caper Mayonnaise:
1	Process the egg yolks, lemon juice and mustard in a food processor until combined. With the motor running, begin adding the oil a teaspoon at a time, processing well after each. When the mixture begins to thicken, gradually add the remaining oil in a thin, steady stream and process until the mayonnaise is thick. Transfer to a bowl, stir through the capers and season with salt and pepper. Stir in just enough water (about 2Tblspns) to think the mayonnaise until it is the consistency of thickened cream.
2	Thinly slice the beef and place on a platter. To serve, drizzle with some of the mayonnaise and serve the remaining mayonnaise seperately.
