Ingredients: 3.3 lbs wild-caught cod or haddock bones and heads, rinsed thoroughly; 8.5 cups filtered water, cold; 2 large carrots, roughly chopped; 1 large yellow onion, quartered, skin on for color; 1 stalk celery, chopped; 4 whole black peppercorns, crushed lightly; 2 bay leaves, dried organic; 1.3 lbs wild-caught cod fillets, skin on, pin-bones removed; 1/4 cup extra-virgin olive oil, cold-pressed, polyphenol-rich; 2 tbsp unsalted pastured butter, softened; 1 tbsp fresh dill, finely chopped; 2 tsp sea salt, flaky; 7 oz dark rye flour, sprouted if possible; 1/2 cup filtered water, warm; 2 tsp extra-virgin olive oil, for dough

This is a reimagined Nordic comfort dish where delicate, wild-caught whitefish is gently poached in a rich, bone-in fish stock until it shreds into a creamy, savory porridge. Served with house-made, seed-oil-free rye crispbread, the dish balances the omega-3 richness of the fish with the earthy fiber of rye, creating a deeply satisfying, anti-inflammatory dinner.

8.5 cupsfiltered water, cold
2large carrots, roughly chopped
1large yellow onion, quartered, skin on for color
1stalk celery, chopped
4whole black peppercorns, crushed lightly
2bay leaves, dried organic

The Porridge

1.3 lbswild-caught cod fillets, skin on, pin-bones removed
1/4 cupextra-virgin olive oil, cold-pressed, polyphenol-rich
2 tbspunsalted pastured butter, softened
1 tbspfresh dill, finely chopped
2 tspsea salt, flaky

Accompaniment

7 ozdark rye flour, sprouted if possible
1/2 cupfiltered water, warm
2 tspextra-virgin olive oil, for dough

Equipment

large heavy-bottomed pot or Dutch oven — essential for maintaining a low, steady simmer without hot spots that could toughen the fish
fine-mesh sieve or cheesecloth — to strain the stock completely clear before poaching
baking sheet lined with parchment paper — for rolling and baking the thin rye crispbread
rolling pin — to roll the rye dough paper-thin for maximum crispness

A little context

Traditional Scandinavian fiskegrøt often relies on a roux made with butter and white flour, sometimes sweetened with a pinch of sugar to balance the salt. We honor the spirit of the dish—warm, comforting, and nourishing—but strip away the ultra-processed flour and refined sugar. Instead, we achieve the creamy texture through the natural gelatin of the stock and the emulsification of the fish flesh, finishing with high-quality EVOO rather than seed oils.

Why this food

The longevity story

The core of this dish is the high concentration of EPA and DHA omega-3 fatty acids from the wild-caught cod, which are critical for reducing systemic inflammation and supporting brain longevity. The slow-simmered fish stock provides bioavailable collagen and gelatin, essential for gut lining integrity and joint health. We enhance the polyphenol load with a generous finish of extra-virgin olive oil and fresh dill, while the rye crispbread offers resistant starch and soluble fiber to support a healthy microbiome without spiking blood glucose.

Method

01
Build the aromatic stock
In a large heavy-bottomed pot, combine the fish bones, heads, carrots, onion, celery, peppercorns, and bay leaves. Cover with 2 L of cold filtered water. Bring to a bare simmer over medium heat, skimming off any grey foam that rises to the top. Once skimmed, reduce heat to low, cover partially, and simmer gently for 45 minutes. Do not boil, or the stock will become cloudy and bitter.
02
Strain the stock
Line a fine-mesh sieve with cheesecloth (or use a very fine sieve) and strain the stock into a clean bowl or pot. Discard the solids. You should have approximately 1.5 L of clear, golden stock. Return the stock to the pot and keep it at a very gentle simmer.
03
Prepare the rye crispbread
While the stock simmers, preheat your oven to 175°C (350°F). In a bowl, mix the sprouted rye flour, warm water, and 10 ml EVOO until a stiff dough forms. On a floured surface, roll the dough as thinly as possible (almost translucent). Cut into squares or diamonds. Place on a parchment-lined baking sheet. Bake for 15-20 minutes until golden and crisp. Watch closely near the end to prevent burning.
04
Poach the fish
Gently lower the wild-caught cod fillets into the simmering stock. The liquid should just barely bubble. Poach for 8-10 minutes, depending on the thickness of the fillets. The fish is done when it is opaque and flakes easily with a fork but is not falling apart yet.
05
Create the porridge texture
Using a slotted spoon, remove the fish fillets to a clean bowl. Let cool slightly. Remove the skin and any remaining bones, then use two forks to shred the fish into large, rustic flakes. Return the shredded fish to the pot of simmering stock. Reduce heat to low.
06
Emulsify and finish
Stir the fish gently into the stock. Add the softened pastured butter (or ghee) and 60 ml of high-quality extra-virgin olive oil. Stir constantly for 2-3 minutes until the fats emulsify with the stock and the mixture thickens slightly into a creamy, porridge-like consistency. Do not boil vigorously. Season with flaky sea salt and stir in the fresh dill.
07
Serve immediately
Ladle the hot fiskegrøt into deep bowls. Serve immediately with the warm, crispy rye bread on the side for dipping or breaking into the porridge. The contrast between the hot, creamy fish and the cold, crunchy rye is essential.

Pro tips

✦Source your fish bones directly from a local fishmonger who cuts whole fish; they usually give them away for free if you ask, ensuring maximum freshness and zero waste.
✦The key to a clear stock is never letting it boil; a bare simmer keeps the proteins from coagulating into a cloudy mess.
✦For the rye crispbread, roll the dough as thin as a sheet of paper; if it tears a little, just patch it with a tiny bit of water. Thinner equals crunchier.
✦If the porridge gets too thick upon standing, simply whisk in a splash of warm stock to restore the creamy texture before serving.
✦Select EVOO with a high polyphenol count (look for harvest date on the bottle) and add it at the very end to preserve the delicate antioxidants.

Substitutions

wild-caught cod → wild-caught haddock or pollock (all three have similar mild flavor and flaky texture suitable for poaching)
pastured butter → ghee or extra-virgin coconut oil (ghee is dairy-free and has a high smoke point; coconut adds a subtle sweetness that pairs well with fish)
dark rye flour → sprouted spelt flour or almond flour blend (for a gluten-free version, though the texture will be less traditional and more crumbly)

Storage

Store the fiskegrøt in a glass container in the fridge for up to 3 days. The rye crispbread should be stored in an airtight container at room temperature for up to 1 week. Reheat the porridge gently on the stovetop with a splash of water or stock; do not microwave aggressively as it can separate the emulsion.

What to serve with it

Hot green tea (sencha or matcha) to aid digestion and add catechins
Sparkling water with a wedge of fresh lemon and a sprig of dill
A glass of dry, cold-climate white wine (e.g., German Riesling Kabinett or Norwegian Pilsner) if alcohol is part of your routine
A small side of fermented pickled cucumbers (homemade, no sugar) for probiotics

FAQ

Why not use canned fish to save time?+

Canned fish often contains added salt, preservatives, and sometimes seed oils. Fresh wild-caught fish provides superior texture, flavor, and a cleaner nutrient profile essential for a Blueprint-aligned diet.

Can I make this ahead of time?+

Yes, the porridge actually improves as the flavors meld. Reheat gently on the stove. However, add the fresh dill and the final glaze of EVOO right before serving to preserve their volatile compounds.

Is the rye bread gluten-free?+

No, traditional dark rye contains gluten. For a gluten-free version, substitute with a certified gluten-free grain like buckwheat flour or a nut-based crust, though the flavor profile will shift.
