This saffron fish soup combines leek, tomato, orange, rice and fresh dill with tender pieces of trout or salmon. The word “soap” in this page’s legacy title is a translation error: this is a savoury soup for eating, not a cosmetic saffron soap recipe. Keeping that distinction clear matters when ingredients include hot stock and fish.
The soup serves four. Prepare all the vegetables before the fish goes into the pot, because the final cooking time is short.
Ingredients
- 1/4 teaspoon saffron threads, finely ground
- 60ml hot water (1/4 cup)
- 2 tablespoons extra-virgin olive oil
- 1 medium leek
- 1 small onion or 2 shallots, finely chopped
- 2 garlic cloves, finely chopped
- 1 litre fish stock (4 cups)
- 120ml fresh orange juice (1/2 cup)
- 75g long-grain rice (about 1/3 cup)
- 2 ripe tomatoes, peeled if preferred and diced
- 500g skinless trout or salmon fillet
- 3 tablespoons chopped fresh dill
- salt and black pepper
- toasted bread, to serve
Fish stock varies greatly in saltiness. Taste it before seasoning and use a low-salt version if possible. In saffron oil cooking, keep the olive oil over low to medium heat; scorching it would overwhelm the delicate saffron and orange.
Brew the saffron
Put the ground saffron in a heatproof glass and pour over the hot water. Cover and leave for 15–20 minutes. There is no need to steam it for an hour: a fine grind, hot water and a covered rest release the colour efficiently. For more detail, see our measured saffron brewing method.
The infusion should smell warm and hay-like, with a clear red-gold colour. Set it aside while preparing the vegetables.
Soften the leek and aromatics
Trim the dark green top and root from the leek. Slice the pale section into thin rounds, separate the layers and rinse them thoroughly; soil often hides between them.
Warm the olive oil in a heavy saucepan over low to medium heat. Add the leek and onion or shallots with a small pinch of salt. Cook for about five minutes, stirring, until soft but not browned. Add the garlic and cook for another two minutes, just until fragrant.
The source version contained mistranslated references to “currant” and “cherry juice.” The cooking sequence points to onion or shallot and sautéed garlic, while the explicitly named fruit in the recipe is fresh orange. Those unclear words have not been turned into extra ingredients.
Cook the rice in the broth
Pour in the fish stock, orange juice and saffron infusion. Stir in the rice and bring the pot to a gentle boil. Reduce to a quiet simmer, partially cover and cook for 20–25 minutes, until the rice is tender.
Add the diced tomatoes during the final five minutes. They should soften while keeping some shape. If the rice absorbs more broth than expected, add a little hot water; the finished dish should still be a spoonable soup.
Add the trout or salmon last
While the rice cooks, check the fish carefully for pin bones and cut it into even 2cm pieces. Lower the pieces into the gently simmering soup. Cook for 2–4 minutes, depending on their thickness, moving them as little as possible so they do not break apart.
The fish is done when it is opaque and separates easily at the thickest point, or reaches 63°C/145°F. Take the pot off the heat as soon as it is ready; residual heat will continue cooking the small pieces.
Season and serve
Fold in most of the dill, taste and add salt and black pepper as needed. The orange should brighten the broth rather than make it sweet. If it tastes too sharp, a little more warm stock will soften it more naturally than sugar.
Ladle the soup into warm bowls, scatter over the remaining dill and serve with toast. A plain sourdough or country loaf is ideal for catching the saffron broth without introducing another strong flavour.
Storage and reheating
Cool leftovers promptly and refrigerate in a covered container for up to two days. Reheat gently over low heat and avoid a rolling boil, which can toughen the fish. The rice will continue to absorb broth in the refrigerator, so loosen the soup with a splash of water or fish stock.
To prepare ahead, make the broth through the rice-and-tomato stage, cool it and refrigerate. Return it to a simmer and add the fresh fish and dill only when you are ready to serve.
Soup, not saffron soap
Someone arriving here after searching for saffron soap should not follow these food instructions as a skincare formula. Soap-making requires a tested formulation and specific chemical-safety controls that are outside this recipe. This page preserves its historical title, but its ingredients and method describe a fragrant saffron soup from beginning to end.
