For starters, you’ll want to grab a rather small saucepan. In it, whisk together your egg yolks and water.
Then, cook (and stir) them over a low and slow heat. You’ll basically want the water to simmer, until you start to see some bubbles formulate along the edges. Which, in my experience, happens around the 20-minute mark, when the temperature reaches around 160°
Then, in another saucepan, mix together the broth (or wine), shallot, vinegar, 1 ½ teaspoons of tarragon, as well as your peppercorns.
Bring all of that to a solid boil, and when it reaches that desired boiling point, reduce the level of heat, and keep those contents simmering (without a cover) for about 10 minutes. You’ll know you’re ready to move on, when you’ve reduced the contents down to about 2 tablespoons or so.
When you see that happen, strain the contents, and place that liquid to the side for the time being.
Now, cut that cold cannabis-infused butter into 8 pieces, and add those pieces to that egg yolk mixture of yours. But only add the infused butter in, one piece at a time, making sure to thoroughly stir it in until it’s completely melted, before adding in another.
Then, take that previously-reserved, set aside liquid, along with your remaining tarragon, and stir all of that into the sauce, as well.
You’re basically done at this point. The only thing left to do is drizzle it atop a prepared steak, and you’re good to go.
