Baroness Tapuzina provides the recipe. Here how to make “Mom’s Creamed Spinach” for four: “Melt the butter in a saucepan and add the onion. Saute the onion until lightly browned and add the flour. Cook until the flour is incorporated with the butter and onion, and is a light brown roux. Add the milk or cream and stir until thickened. Add the spinach and cook on medium low heat, stirring until the spinach is defrosted. Add the nutmeg and mix thoroughly in the spinach. Cook until hot.”
Might be the French/Italian influence but that fish looks like frog ready to jump out. Can you see the legs on the left? Hmm, nuts with garlic, I need to try that, I like how it sounds. And what is “red fish”, what fish would that be?
