Instructions
- Bring a medium saucepan half-full of water to a light simmer, with a two-cup Pyrex measuring cup sitting in the middle.
- Melt the butter in the measuring cup.
- Remove the measuring cup from the saucepan and add the lemon juice (fresh or bottled is fine) to bring the temperature of the butter down a bit.
- Slowly pour the butter-lemon mixture into the bowl that contains your egg yolks, whisking constantly to prevent curdling the eggs. (This is the "tempering the eggs" part).
- Pour the mixture back into the measuring cup and return to the saucepan.
- Cook over medium/medium-low heat (water bath should be a low simmer) for 10 minutes or so or until the sauce thickens, stirring frequently with a fork or whisk. Every minute or two should be fine - this does not require constant whisking.
