If you want to make a dish that’s a little exotic and impressive yet very easy, fish baked in salt might be your answer! This absolutely delicious preparation has a very lightly seasoned taste. Contrary to popular belief, the meat is not extremely salty. The salt bakes into a crust that is easily removed and outside the skin. The meat itself is delicate and moist because it basically steams inside the salt crust.
For starters, you will need a very large roasting pan and a lot of salt. It’s difficult to say how much because it depends on the size of your pan and the size of your fish. Generally, for one large fish you will need two boxes of kosher salt and 4 egg whites. (You can get kosher salt at Kroger or any grocery store for a few dollars a box.)
The fish should be completely whole with the skin on – and yes, also with the head on. Snapper, salmon and other larger fish work best, but you can also use trout or other smaller fish like mackerel. Smaller fish can be cooked together in the same crust – as many as will fit in your pan. You can cut off the heads and peel the skin away before you serve it. Just as an aside, when you are shopping for your fish, make sure it will fit in your pan and that your pan will fit in your oven. Don’t ask me how I know that.
If you want to get really fancy, you can crack the crust and serve the fish at the table. I don’t recommend that though because salt tends to fly around and it – well – it makes a mess. But anyway, back to the basics.
To bake fish in salt, first clean your fish (no guts), wash it and pat it dry. Measure the thickest part of the fish. Then mix the salt with the egg whites. Use enough egg whites so the salt is slightly moist. Put 1/2” salt in the bottom of your pan. Put the fish on top of that. Cover the fish with ½” of the salt/egg white mixture. Make sure that the fish is completely buried. Bake in a preheated 425 F oven, 10 minutes per inch of fish.
Remove from the oven and let stand 10 minutes. Then crack the crust and serve the deliciously tender and moist fish meat that you find inside. (I often do this in or near the sink to catch flying salt.) Enjoy!
