Preheat oven to 300 degrees F.
Prepare the broth, mixing it in a bowl with the clam juice, onions, thinly sliced potato, saffron and the water.
In an 8-inch oven pan, set the codfish, lightly dusted with flour. Cover with the broth and cook for 10 minutes.
Remove it from the oven and reduce the sauce on the stovetop to the desired consistency.
In a separate bowl, mix the smashed garlic, the olive oil, parsley, dill, and red pepper. Use it to dress the fish before serving.
Blanch the string beans separately and compliment the dish as a topping. Garnish with chives and dill.
