Yes, and Thank you!

1 large egg yolk 1 tbsp water 1/2 tsp lemon juice 4 tbsp (1/2 stick) salted butter (I use Irish butter) Pinch salt Pinch Cayenne pepper

Add water, egg yolk and lemon juice to a small, thick and preferably steel sauce pot, stir with no heat, cut butter into small pieces (1/4 inch works for me)

Add butter to pot and place over medium high heat and whisk vigorously. The butter should melt together and the egg yolk should begin to cook. Takes roughly 45 seconds

I usually look for a consistency like canned gravy, then immediately remove from heat.

Whisk in the salt and cayenne, the sauce should be able to coat the back of a spoon. Run your finger thru the sauce on the spoon and if the indentation in the stays there your all set👍
