Add your egg yolks and salt to a wide mouth pint size mason jar. Use your immersion blender to blend the egg yolks for 30 seconds.
In a measuring cup with a pour spout, combine the melted ghee, water and lemon juice. Stir to combine.
With your immersion blender running the whole time in your mason jar, slowly pour in the melted ghee mixture. Lift your immersion blender and press it back down every 5 seconds to help the liquid emulsify. Continue until all the melted ghee mixture is added.
Taste for salt and lemon juice, adding more if desired.
Serve the mixture warm on top of poached eggs, vegetables, salmon, chicken or fish.
Will keep for 1 week refrigerated in a mason jar.
To warm from the fridge, microwave 1 cup of water for 3 minutes in a 2 cup measuring cup. Place the mason jar in the warm water to create a water bath. Shake the jar every minute or so, until the mixture is warm.
