2 fresh poblano chiles (6 oz. total), stemmed, seeded (see
1/4 cup packed, coarsely chopped fresh cilantro, plus about 2 tbsp. whole leaves
1/2 cup reduced-sodium chicken broth
3/4 cup sour cream, divided
1 to 2 tbsp. lime juice
1 or 2 boned and skinned halibut or salmon fillets (1 3/4 lbs. total; about 1 in. thick)
How to Make It
Preheat oven to 375°. In a large frying pan, melt butter over high heat. Stir in flour, remove from heat, and mix to form a smooth paste.
Scrape flour paste into a blender. Add tomatillos, onion, chiles, chopped cilantro, chicken broth, and 1/2 cup sour cream. Whirl until smoothly puréed. Pour green sauce back into frying pan; add salt and lime juice to taste.
Rinse fish, pat dry with paper towels, cut into 6 equal pieces, and season with salt. Set pieces slightly apart in an 8- by 12-in. baking dish.
Bring green sauce to a boil over high heat, stirring. Pour evenly over fish.
Bake fish until it flakes but still looks moist in the center of the thickest part (cut to test), 15 to 20 minutes.
With a wide spatula, transfer fish to plates. Spoon sauce over portions, top with small spoonfuls of remaining sour cream, and sprinkle with cilantro leaves.
How Hot Is Your Chile? To assess a chile's heat, slice off its top through the ribs and seeds, where the heat-producing compound capsaicin is concentrated. Touch the slice to your tongue. If you want your food to be milder, split the chile and scrape out all or some of the ribs and seeds. If your skin is sensitive, wear kitchen gloves or hold the chiles with a fork—and don't touch your eyes.
I made it for my boyfriend one Friday night and he was WOWED to say the least. He eats to LIVE as I LIVE to eat, and with that said he asked for seconds with this meal, totally not like him to eat more then one serving of anything! First I used Halibut then cleaned out my baking dish and served him Salmon; just as amazing!
~oh and instead of the two tablespoons of lime that it calls for, I used an entire half~
This was simply wonderful: easy, very flavorful, low calorie, and lovely. The creaminess of the sauce was a perfect complement to the firmness of the halibut (I had one piece of cod to use, and it was equally delicious). This went immediately into my "favorites." I served it with a brown/red/wild rice medley (also good with the sauce) and steamed green beans. Scrumptious and filling.
