Don't let the idea of making Béarnaise Sauce scare you away. It is actually very easy as long as you adhere to a couple of rules.
You want to be careful not to cook the egg before the egg and butter emulsify.
- To avoid that you are going to heat a few inches of water in a saucepan. Then you are going to set a bowl over the pan. The bowl should settle about halfway down the saucepan but the key is to make sure the bottom of the bowl does NOT touch the water.
- You are going to whisk the egg yolks with the wine reduction CONSTANTLY. They will get foamy and thicken and lighter in colour.
- The melted butter must be cooled down. It can be warm to the touch but not hot. You are going to add the butter to the egg yolk mixture off the heat whisking constantly.
- You can hold the sauce a few hours at room temperature but be careful if you are going to reheat. It needs to reheat gently again, in the bowl over the saucepan - with the bowl NOT touching the water.
If you stick to these 'rules' you should be good to go. But the sauce gets too hot the sauce will 'break' and go grainy. It still will taste okay but the texture is less appealing.
