Mary Berry’s Fillet Tails Of Beef With Bearnaise Sauce And Rocket Salad

This is by no means a foolproof bearnaise sauce recipe. It should include the following instructions: \”Whisk the reduced liquid, eggs and salt for several minutes until the sauce starts to thicken … AND ONLY THEN start adding the cubes of butter one at a time. Otherwise it doesn\’t thicken up at all. You end up with a bowl of melted butter that tastes OK but it would be too embarrassing to give to your guests.
