Fill a large pot 1/3 of the way with water and bring to a boil. Lower the heat to a simmer and place a large heatproof bowl on top. Make sure the bottom of the bowl is not touching the water.
Add the egg yolks, sugar, lemon zest, lemon juice and salt to the bowl and use a whisk to combine. Continue whisking (don’t stop otherwise the eggs will curdle) until the mixture begins to thicken and coats the back of a spoon. It will resemble a thick hollandaise sauce.
Remove the bowl from the heat and add the butter in three batches whisking with each addition until the butter is completely melted and combine before adding the next batch of butter.
Store in a jar with a lid in the fridge for up to 2 weeks.
