If I had to choose my all-time favorite restaurant dishes, the smoked haddock chowder from The Spotted Pig would definitely be on there, possibly in the top five. Years after I asked Ed Levine of Serious Eats if he could get the recipe, he finally posts the recipe for me.
When infusing the haddock, think of making a cup of tea. You want to pull all the smoky flavors out into the cream. This will result in a deeply rich soup. Once you make this you will never go back to another chowder.
Thank you Ed and April! (I'm really holding back on the exclamation points here; I'm almost irrationally excited to cook this for dinner tomorrow night...if I can find smoked haddock somewhere in NYC...)
