[Crawfish tails in Sauce Nantua]
This is an exhausting dish originally created by Chef M. Hure. I mean that in the best way possible. It requires a lot of prep work, a lot of skill, and takes forever. But the result is delicious and the new skills of making crawdaddy butter and sauce Nantua will serve you well. However, if you like to spend all day prepping and setting up a meez and just getting nerdy in the kitchen, then welcome to your new favorite.
There are six steps to this dish:
- The fish stock
- Cooking the crawdad tails
- crawdad butter
- sauce nantua
- sauce hollandaise
The tails are no big deal. And you’ve made Hollandaise so, you know, show no fear.
You can buy fish stock. You can. But if you do you’re a goddam cheater. You’re going to go to your fish monger anyway to get the écrevisses so pick up some heads and bones while you’re there. Trust me, the look of mild respect on your fish guy’s face is worth it. HOWEVER, if your fish guy makes stock, then fuck it, pick up that stock. But don’t use the stuff from the store. It blows and making your own is fucking worth it.
Unless you live in Louisiana, you’re probably not going to pick up fresh crayfish. You’re getting frozen. Don’t sweat it. Half the cafes in New Orleans do the same thing. Get more than you need so you can freeze the butter for other dishes.
The work in this dish comes from making the crayfish butter and the sauce Nantua. Sauce Nantua is béchamel sauce with crayfish butter added. How I have lived so many years without the knowledge such a divine thing exists, I’ll never know. It is a testament to the deprivation of my childhood and the depravity of my youth that I’ve managed to avoid Sauce Nantua. I would put it on everything. I would put it on grits, I swear to God.
