Poached Whitefish in Butter & White Wine Sauce (A.K.A. “Boiled Trout”)

I love cooking historic recipes. Whether it’s traditional Irish soda bread from the 1800’s, or Chicken Pilaf with Cilantro circa 1930’s America. Old recipes fascinate me. This recipe for poached whitefish is an adaptation of a 1670’s recipe from Martha Washington’s Booke of Cookery originally titled “Boiled Trout”.

The thing about recipes from this era is that they don’t contain incredibly detailed instructions. It’s common to see the author say “add a pinch”, or use a bit of this”, and not give a specific measurement.

In this recipe, Mrs. Washington simply says to “use as much butter and white wine as desired, and as much salt as is needed to season the sauce.”

If you think about it, this makes a lot of sense. She probably had to vary the recipe every time trout was available, depending on how large the catch was for the day. So it’s far more about method and the amounts of herbs and spices that Mrs. Washington had on hand at the time.

Enough with history, let’s make poached whitefish!

This recipe is primarily about 2 things, bread and sauce. Yes, the fish is the key flavor component, but the bulk of the meal is actually in the toasted bread, or “sops.” I would assume that in the time this was originally made these would have been full-sized slices of bread, but for this poached whitefish recipe we’ll be using baguettes.

Gather together your ingredients. You’ll need some bread, some salt, some good quality butter, about 2-inches (3 cm) worth of fresh ginger, a few sprigs of fresh rosemary, a little white wine, and of course, some fish.  I used Swai fillets for this recipe, but any whitefish will do here, so feel free to use cod, trout, tilapia, milk fish, or whatever you happen to have available.

Whitefish fillets, crusty bread, Irish butter, white wine, fresh ginger and fresh rosemary.

First, cut your bread into fairly thick slices. We’ll be using this to soak up all the amazing sauce we’re creating, so they need to be a bit sturdy.

Slice rounds of a crusty Baguette to make croutons for poached whitefish in white wine sauce.

Then chop up your whitefish into about 1-inch cubes. (Though I’m sure this recipe would work with whole fillets, also.)

Cut whitefish (In this case, it's swai fillets) into cubes, if desired. Or you could just poach the fillets whole.

Butter your sops in a heavy pan and toast until golden, then set aside.

Toast baguette rounds in a little butter to make croutons or soppettes to pour our lovely sauce over.

In the same pan, add your white wine, butter, ginger, rosemary, and salt to taste. Bring it all to a boil.

Add wine, butter, ginger, rosemary, and a sprinkle of pepper to the skillet.

Turn off the heat, add the fish and baste until just cooked through. (About 2 minutes.) You’ll know it’s done when it’s just barely opaque all the way through.

Remove herbs, reduce heat to simmer, and add fish. Baste until cooked. (About 3 minutes.)

Then, just pop your lovely little croutons into a bowl or on a plate, and spoon a heaping helping of poached whitefish and as much of the amazing sauce as you’d like. It’s that simple, but it’s far more amazing to taste than it is to look at.

Before I get to the recipe, I’d like to share the video that inspired it. This comes from Townsends, a YouTube channel dedicated to historical recreations and recipes. It’s well worth your time, so much so that I went down a rabbit hole while going to get the link when I realized there were a few new videos. It’s a ton of fun and I highly recommend it.

Here’s the original video for “Boiled trout”

I think my version does credit to Mrs. Washington, and to Mr. Townsend. I hope you agree.

What I would have done differently:

Yeah. About that. Nothing.

This recipe is about as simple as it gets but it’s also as amazing as anything you’ll find in a great restaurant. The fish is perfectly cooked, tender, and so full of flavor that I have a hard time describing it without resorting to words like foodgasm.

It may not look like much, but it’s everything you could want in a main dish and more. Seriously, just look at this!
