6. Simmer until potatoes are nearly tender, about 15 minutes.
7. Cut the rainbow trout fillets into bite-sized pieces and gently add to the pot.
8. Cook for another 5 minutes until the fish is just cooked through but still tender.
9. Add 200ml of cream and a handful of fresh dill.

What are the essential ingredients for Finnish rainbow trout soup?

The hallmark of traditional Finnish rainbow trout soup lies in its few but quality ingredients, with premium rainbow trout taking center stage. Here’s what you’ll need for an authentic version:

• Rainbow trout fillets (500g) – The star ingredient that provides the soup’s delicate flavor profile. LOHI Earth’s rainbow trout fillets are ideal as they’re sustainably raised in clean environments.
• Potatoes – Traditional Finnish varieties like Nicola or Rosamunda work best, but any firm potato will suffice.
• Carrots – For subtle sweetness and traditional color.
• Onion – Provides aromatic foundation for the broth.
• Fish stock – Creates depth of flavor.
• Heavy cream – Adds richness and smoothness.
• Fresh dill – The quintessential herb in Nordic fish dishes.
• Butter – For sautéing and adding richness.
• Allspice berries – The traditional Finnish spice for fish soups.
• Bay leaf – Adds subtle aromatic notes.
• Salt – To taste.

Modern variations might include leeks, fennel, or white wine, but the quality of the rainbow trout remains paramount. LOHI Earth’s ready-to-cook fillets ensure optimal texture and clean flavor, making them perfect for this delicate soup.

How long does it take to make Finnish rainbow trout soup?

The complete preparation and cooking process for Finnish rainbow trout soup typically requires approximately 45 minutes from start to finish. Here’s how that time breaks down:

• Ingredient preparation: 15 minutes (cleaning, peeling, and chopping vegetables)
• Initial cooking of vegetables: 15-20 minutes
• Cooking fish and finishing the soup: 10 minutes

Using LOHI Earth’s pre-packaged rainbow trout fillets significantly reduces your preparation time, saving you approximately 10-15 minutes that would otherwise be spent scaling, filleting, and deboning the fish. These ready-to-use fillets allow you to focus on perfecting the broth and vegetable base of your soup.

The relatively quick cooking time makes this dish suitable for both weeknight dinners and special occasions. For the best flavor development, some Finnish home cooks suggest letting the soup rest for 5-10 minutes before serving, allowing the flavors to meld perfectly.

What makes Finnish rainbow trout soup different from other fish soups?

Finnish rainbow trout soup distinguishes itself from other fish soups worldwide through several distinctive characteristics. Unlike Mediterranean fish soups that often incorporate tomatoes and various herbs, or Asian varieties with coconut milk and spices, Finnish kalakeitto embraces simplicity with a focus on clean flavors.

The defining features include:

• Minimal seasoning – relying primarily on dill, allspice, and salt
• Cream-based broth rather than tomato or clear broth
• Focus on the natural flavor of rainbow trout rather than masking it
• Use of root vegetables indigenous to Nordic climates
• Absence of wine or acidic components common in other European fish soups

Rainbow trout itself contributes uniquely to this soup with its delicate texture and mild, slightly sweet flavor that doesn’t overpower the other ingredients. The flesh of rainbow trout holds together well in the soup while still remaining tender, unlike oilier fish that might dominate the flavor profile or flakier varieties that disintegrate during cooking.

What side dishes pair well with Finnish rainbow trout soup?

Traditional Finnish rainbow trout soup forms the centerpiece of a meal that celebrates Nordic culinary heritage. The perfect accompaniments enhance the dining experience without overwhelming the delicate flavors of the soup.

Classic Finnish pairings include:

• Ruisleipä (Finnish rye bread) – Dense, dark rye bread served with butter creates an ideal contrast to the creamy soup
• Archipelago bread – A sweet-savory malt bread traditional to coastal Finland
• Fresh herb butter – Often featuring dill, chives or lemon zest
• Simple green salad – With a light vinaigrette to cleanse the palate
• Pickled cucumbers – Adding a tangy contrast to the rich soup

For beverages, consider Finnish beer, a crisp white wine, or traditional Finnish kotikalja (a mild, low-alcohol malt beverage). These complement the delicate flavor of LOHI Earth’s sustainably sourced rainbow trout while honoring Finnish culinary traditions.

For a complete Finnish experience, serve the soup as part of a larger meal beginning with smoked fish appetizers and ending with seasonal berry desserts.
