Winter is the best time of the year to eat "lake", or
burbot. Burbot are related to cod and live in the cold, dark, freshwater lakes of northern Sweden. They can, of course, be eaten year round. However, burbot spawn midwinter and therefore are full of roe between December and February.
Burbot isn’t very popular in Sweden anymore. I bought this fish at giveaway prices and the fishmonger seemed surprised that I’d want it. He seemed downright suspicious when he noticed my accent but quickly warmed up when I mentioned that burbot, due to its slimy coating (the slime insulates them) and general low status amongst fishermen, are also known as “lawyers” in the Northern U.S. He even offered to inspect his four burbots to find the one with the most roe. Alas*, it seems I was a few weeks late in my searches as none of the burbots he had contained any roe.
Back in its day, burbot was a pretty popular fish. Burbot can be caught by any number of means but one method was especially popular for generations of poorer Swedes. In midwinter, burbot swim from their deep lairs to spawn in shallow, shoreline waters. And, with the right conditions (i.e., clear, snow-free ice), burbot can be stunned by smaking the ice with a sledge. Apparently, one does not want to hammer through the ice but instead simply crack a “rose” in it. This stuns the burbot. One then may make a hole in the “rose” and retrieve the fish.
And, finally, there is one aspect of the burbot that makes it especially appropriate for survival food: its liver. Burbot liver is both huge (up to 10% of its body weight) and packed full of vitamin D.
To the pictures!
The burbot:
its liver:
Start by filleting the burbot and setting aside the fillets along with the liver (and roe, if your burbot hasn’t spawned yet).
With the scraps, bones and trimmings, make a quick stock. I simply rinsed the scraps in cold water and simmered them for about 45 minutes with ½ carrot, a little leek, 1 stalk of celery, a bay leaf and some thyme.
The ingredients for the final dish:
An onion, 1 stalk of celery, 1 small carrot, ½ of a leek, about 20 haricot verts (or, say 10 green beans), 1 tablespoon lemon juice, the burbot fillets and liver (about 1 ½ pounds – cod would make a fine substitute), one whole mace “flower” (maybe ½ tsp ground?), one bay leaf, ½ tablespoon instant-blending flour, ¾ cup white wine, 2 ½ cups of the burbot stock, 1 cup heavy cream or half & half, 2 egg yolks, about ½ cup broccoli florets (or peas or other green vegetable). Not pictured: 1 tablespoon white wine vinegar
Start by adding the wine, lemon juice, white wine vinegar, mace and bay leaf to the stock and bringing it to a simmer.
Add the fillets and the liver and simmer for 10-15 minutes.
While the fish is simmering, finely chop the onion, carrot, celery and leek and haricot verts:
Remove the fish (keep warm) and strain the stock. Bring the stock back to a boil and reduce by half.
When reduced, add the cream…
… and chopped vegetables:
Simmer for about 5 minutes.
Next, thicken the sauce. Start by adding the instant-blending flour:
Whisk in the flour and let the sauce thicken for a few minutes. Remove the sauce from the heat and add (while whisking) the two egg yolks. Taste and add salt and pepper as needed.
Place a serving of fish and liver on a plate, coat with sauce and vegetables, garnish and serve:
All in all, an excellent dish. The burbot (both the liver and the fillets) is mild tasting and, apart from its firmness, could easily be substituted with any type of cod or firm whitefish. The sauce was very rich and I’d probably recommend using half-and-half for anyone even a little sensitive to rich dishes. Finally, the mace makes for an interesting spice. I’m normally not wild about mace by itself (too much of it makes everything taste like ketchup to me) and was concerned after tasting the poaching liquid. However, once thickened and full of fresh-tasting vegetables, the mace flavor had kindly retreated to the background.
* I use “alas” lightly here. As I’ve mentioned elsewhere, I’ve become more and more squeamish about eating fish roe as report after report of collapsing fish stocks hits the newsstands.
