For this healthy fish recipe, you steep corncobs in milk; the resulting "stock" boosts the intensity of made-from-scratch creamed corn, plus extra starch from the corn contributes to its thick texture. This recipe calls for halibut—line-caught from the Pacific Ocean is the most sustainable option. Can't find it? Swap in Pacific cod or U.S. farmed tilapia instead. Serve this summery combination of seared fish, corn, tomatoes and basil for weeknight family dinners or to company on the weekends.
