Directions
Method written by CompKitchen from the ingredient list. Not the original author's method, not kitchen-tested.
Make the rouille first: in a bowl, whisk the eggs with the Dijon mustard, 4-6 crushed garlic, a pinch of sea salt and a squeeze of lemon juice. Use pasteurized eggs since this is not cooked. Whisk in the vegetable oil a few drops at a time, then the extra virgin olive oil in a thin stream, until thick. Stir in the saffron steeped in a spoon of warm water, and refrigerate.
Thinly slice the shallots and the 2 garlic. Warm the olive oil in a large pot over medium heat, add the shallots and garlic, and cook for 5 minutes until soft.
Chop the tomatoes and add them with the thyme sprigs, the Pastis and the white wine. Simmer for 3 minutes, then cover with water and simmer gently for 10 minutes.
Season the broth with sea salt and freshly ground black pepper. Add the red mullet pieces and simmer for 4 minutes, then add the prawns and langoustines and cook 3 to 4 minutes more until the flesh is opaque and flakes, at least 145°F (63°C).
Remove the thyme stalks. Toast the bread slices until golden.
Ladle the soup into bowls, scatter with chopped parsley, and serve with the toasted bread spread with rouille.

Fit is the average pairing score against garlic, egg, olive, lemon, shallot, tomato, thyme. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
