Charred Sourdough & Herring Butter (Swedish) | Arteflame

Introduction

There is something primal and deeply satisfying about eating with your hands, especially when it involves warm, smoke-kissed bread. This Grilled Sourdough with Matjes Herring Butter transports me straight to the Swedish coast on a midsummer evening. Imagine the scent of the ocean mixing with the aroma of **wood fire** as you smear cool, savory butter onto hot, crunchy toast. It is a study in contrasts: hot and cold, creamy and crunchy, earthy and briny. This isn't just an appetizer; it is a rustic experience that wakes up the palate in the most delightful way, perfect for sharing with friends around the fire.

Why It's a Summer Essential

I adore this recipe because it transforms humble ingredients into a **sophisticated umami bomb**. The Matjes herring brings a sweet-savory depth that pairs perfectly with the sharpness of red onion and fresh dill. Using the **Arteflame grill** is the secret weapon here; the high heat of the flat cooktop creates a caramelized crust on the sourdough that a toaster simply can't replicate. It looks impressive but comes together in minutes, making you look like a pro with minimal effort.

Chef's Tips for Perfection

• Soft Butter is Key: Make sure your butter is completely at room temperature before you start. If it is too cold, the herring and herbs won't mix evenly, and you will lose that silky texture.
• Watch the Heat: Sourdough has natural sugars that caramelize fast. Keep a close eye on your bread on the steel cooktop to get those beautiful char marks without burning the toast.

Make It Your Own

If Matjes herring isn't your thing, **hot-smoked salmon** is a fantastic alternative that offers a similar texture. For a vegetarian twist, swap the fish for chopped capers and dulse flakes to keep that briny, oceanic kick without the seafood.

Ingredients

• 1 loaf of rustic Sourdough bread, thick-sliced
• 200g (7 oz) Unsalted butter, softened at room temperature
• 150g (5.3 oz) Matjes herring fillets, drained and finely chopped
• 1 small Red onion, finely minced
• 1 bunch Fresh chives, finely chopped
• 1/2 bunch Fresh dill, chopped (plus extra for garnish)
• 1 tbsp Fresh lemon juice
• 1 tsp Freshly cracked black pepper
• Olive oil or melted butter (for brushing the bread)
• Sea salt flakes (optional, for finishing)

Instructions

Step 1: Create the Herring Compound Butter

1. Begin by ensuring your butter is completely soft and pliable; this is crucial for an even mixture. Place the butter in a large mixing bowl and whip it slightly with a fork or spatula to loosen the texture.
2. Add the finely chopped Matjes herring, minced red onion, chopped chives, and fresh dill to the bowl.
3. Pour in the fresh lemon juice and add the cracked black pepper.
4. Fold all the ingredients together thoroughly until the herring and aromatics are evenly distributed throughout the butter.
5. Transfer the mixture to a serving bowl or roll it into a log using parchment paper. Refrigerate for at least 30 minutes to let the flavors meld, but remove it 10 minutes before serving so it spreads easily.

Step 2: Fire Up the Arteflame Grill

1. Build a medium-sized fire in the center of your Arteflame grill. You are looking for a consistent heat across the flat steel cooktop.
2. Allow the cooktop to reach searing temperature. The steel should be hot enough that a drop of water sizzles and evaporates instantly.
3. Lightly oil the cooktop surface using a paper towel dipped in vegetable oil to ensure a non-stick surface for the bread.

Step 3: Char the Sourdough

1. Brush both sides of your thick sourdough slices generously with olive oil or melted butter. This encourages caramelization and prevents the bread from drying out.
2. Place the slices directly onto the flat steel cooktop. Position them closer to the center fire for a deeper char, or further out for a slower toast.
3. Grill for approximately 2 to 3 minutes per side. You want to achieve a golden-brown crust with distinct char marks, while keeping the inside slightly soft and chewy.

Step 4: Assembly and Serving

1. Remove the bread from the grill and place it immediately on a serving board while it is still steaming hot.
2. Take a generous dollop of the room-temperature herring butter and spread it over the hot bread.
3. Allow the residual heat from the toast to slightly melt the butter, releasing the aroma of the dill and onion.
4. Garnish with extra fresh dill and a sprinkle of sea salt flakes if desired. Serve immediately.

Tips

To master this Swedish classic, temperature management is your best friend. Ensure your butter is truly at room temperature before mixing; if it is too cold, the herring and onions won't incorporate evenly, resulting in a clumpy spread. Conversely, when grilling the sourdough on the Arteflame, watch the bread like a hawk. Sourdough contains sugars that can go from perfectly caramelized to burnt in a matter of seconds on high heat. If you prepare the butter a day in advance, the flavors will have more time to marry, resulting in a deeper, more cohesive taste profile. Just remember to pull the butter out of the fridge at least 20 minutes before serving, as the contrast between the hot, crunchy bread and the soft, melting butter is essential to the textural experience of this dish.

Variations

While the traditional Matjes herring combination is a Swedish staple, this compound butter concept is incredibly versatile and can be adapted to suit different palates or dietary preferences. If herring feels too bold for your crowd, you can easily swap the protein or shift the flavor profile entirely while keeping the sourdough base. Experimenting with different cured fish or even vegetarian options can breathe new life into this appetizer. Here are a few distinct variations you can try on your grill:

• The Anchovy & Garlic Twist: Swap the herring for high-quality anchovy fillets and add roasted garlic for a punchier, Mediterranean savory kick.
• Smoked Salmon Whip: Replace the herring with hot-smoked salmon and swap the red onion for capers for a classic brunch-style flavor.
• Vegetarian Seaweed Butter: Omit the fish entirely and use dulse flakes or crushed nori sheets with sea salt to mimic the oceanic brine without the seafood.
• Spicy Citrus Butter: Add chili flakes and extra lemon zest to the herring mixture for a variation that cuts through the richness with heat and acid.
• Bacon & Maple: For a non-seafood meat lover's version, use crispy crumbled bacon and a dash of maple syrup instead of herring.

Best pairings

This dish is an umami bomb, rich in fat and salt, which means it requires beverages and sides that can cut through the richness and cleanse the palate. In true Scandinavian fashion, the most authentic pairing is a chilled glass of Aquavit. The caraway and dill notes in the spirit mirror the herbs in the butter perfectly. If strong spirits aren't your preference, a crisp, dry Pilsner or a Lager works wonders to wash down the salty fish and butter. For wine lovers, a high-acid white wine like a Riesling or a Grüner Veltliner provides the necessary brightness to balance the dish. regarding side dishes, think fresh and acidic. A cucumber salad with vinegar and dill, pickled radishes, or a simple beet salad will provide a refreshing crunch that contrasts beautifully with the warm, heavy bread and butter.
