6 egg yolks
3 sticks butter, cubed (24 tbsp)
3–6 tsp lemon juice
Place the egg yolks in a heatproof glass bowl.
Heat the butter in a saucepan until foaming, then pour gradually onto the egg yolks, whisking all the time.
Add the lemon juice to taste, then pour into a heatproof measuring cup.
Keep the sauce warm while you are waiting to serve it.*
*Half-fill a saucepan with hot water from the kettle and place the cup of hollandaise in the saucepan to keep warm. When the water cools, just put the saucepan on a gentle heat, but do not let the water boil too long or the sauce will scramble. It will sit quite happily like this for a couple of hours.
Note: Ingredients can be divided to suit portions desired.
