Grilled Sourdough with Laverbread Butter (Welsh Style) | Arteflame

Introduction

There is something primal and deeply satisfying about the scent of toasted bread mingling with the salty, oceanic aroma of seaweed. This Grilled Sourdough with Laverbread Butter transports you straight to the rugged Welsh coast. The contrast between the hot, smoke-kissed sourdough—crisped to perfection on the Arteflame—and the cool, melting richness of the "Welsh Caviar" butter is pure magic. It’s an appetizer that feels fancy but is incredibly grounded, perfect for impressing guests around the fire or enjoying as a rustic snack on a breezy evening.

A Taste of the Coast

I love this recipe because it transforms humble ingredients into a gourmet experience with zero fuss. It’s an umami bomb thanks to the laverbread, which isn't actually bread but a nutrient-dense seaweed puree. When slathered on artisan sourdough seared on the carbon steel cooktop, you get a depth of flavor that a standard toaster just can't replicate. It’s rugged, elegant, and serves as a fantastic conversation starter about culinary heritage.

Chef's Notes

• Watch the Heat: Place your bread midway between the fire and the edge. You want a deep golden char, not burnt toast.
• Prep Ahead: Make the compound butter a day in advance. This allows the seaweed flavor to fully permeate the dairy for a richer taste.
• Butter Quality: Since there are so few ingredients, use the highest quality salted European butter you can find.

Swaps & Tweaks

If you can't find traditional Laverbread, finely chopped nori sheets rehydrated in a little water can work in a pinch. For a gluten-free option, swap the sourdough for a sturdy GF baguette that can handle the grill heat without crumbling.

Ingredients

The Essentials

• 1 Loaf of fresh, high-quality Sourdough bread (sliced thick)
• 1 tin (approx. 120g) of prepared Laverbread (laver seaweed paste)
• 250g Salted Butter (softened to room temperature)
• Sea salt flakes (Maldon or similar for finishing)
• Freshly cracked black pepper
• Olive oil (for brushing the grill)

Instructions

Step 1: Prepare the Laverbread Butter

1. Ensure your butter is completely softened to room temperature to allow for easy mixing.
2. In a mixing bowl, combine the 250g of salted butter with the tin of laverbread.
3. Use a fork or a spatula to fold the seaweed into the butter until it is evenly distributed, creating a beautiful marbled dark green appearance.
4. Season with a pinch of black pepper. Since laverbread and salted butter are already savory, taste before adding extra salt.
5. Roll the butter into a log using parchment paper and chill in the refrigerator if you prefer firm rounds, or leave it soft for spreading directly.

Step 2: Fire Up the Arteflame

1. Build a medium-sized fire in the center of your Arteflame grill using dry hardwoods like oak or hickory.
2. Allow the grill to burn down until the center cooktop reaches a searing temperature (over 400°F) and the outer edges are moderately hot.
3. Scrape the cooktop clean and apply a thin layer of olive oil to season the steel, ensuring a non-stick surface for your bread.

Step 3: Grill the Sourdough

1. Slice your sourdough loaf into thick, hearty slabs, approximately 1 inch thick.
2. Place the slices directly onto the flat steel cooktop. Position them midway between the center and the edge to avoid burning them instantly.
3. Toast the bread for 2 to 3 minutes per side. You are looking for a deep golden-brown crust with distinct char marks and a warm, soft interior.
4. Move the bread to the cooler outer edge of the grill to keep warm without further browning if you are managing a large batch.

Step 4: Assemble and Serve

1. Remove the toasted sourdough from the grill while it is still piping hot.
2. Immediately slather a generous amount of the room-temperature laverbread butter onto the bread. The heat from the toast should melt the butter, allowing the seaweed essence to soak into the crumb.
3. Sprinkle with a few flakes of sea salt for crunch and serve immediately.

Tips

To master this Welsh delicacy on the Arteflame, temperature management is key. The beauty of the Arteflame is its heat zones; keep the fire central and intense, but toast your bread on the middle ring of the cooktop. If the steel is too hot, the sourdough will char on the outside before warming through. Conversely, if it is too cool, the bread will dry out rather than crisp up. For the best flavor profile, source traditional Welsh Laverbread if possible, as its processing method retains the oceanic minerality better than generic dried seaweed.

Additionally, do not shy away from the butter quality. Since this recipe relies on only three main components—bread, seaweed, and butter—the dairy acts as the carrier for all the flavor. Use a cultured, high-fat butter (European style) for the richest mouthfeel. If you are preparing this for a crowd, you can make the compound butter up to a week in advance; the flavors will meld and deepen while sitting in the fridge.

Variations

While the traditional recipe is a purist's delight, the earthy and salty profile of laverbread butter serves as an excellent canvas for culinary experimentation. You can easily tweak the compound butter to suit different main courses or personal preferences without losing the soul of the dish. Here are a few ways to customize your grilled sourdough experience:

• Citrus Zest: Fold in the zest of one lemon to cut through the richness of the butter, making it perfect for seafood pairings.
• Spicy Kick: Add a pinch of chili flakes or cayenne pepper to the butter mixture for a subtle heat that lingers after the umami hit.
• Garlic Infusion: Roast a head of garlic on the Arteflame, mash the cloves, and mix them into the laverbread butter for a savory garlic bread twist.
• Herb Garden: Mix in chopped fresh parsley or chives to add a fresh, herbaceous brightness to the deep seaweed flavor.
• Fried Bread: Instead of dry toasting, melt some bacon fat on the cooktop and fry the sourdough slices in it before adding the butter.

Best pairings

Laverbread butter is incredibly versatile and pairs magnificently with proteins that benefit from a saline, umami boost. Because of its strong connection to the sea, it naturally complements seafood, but its richness allows it to stand up to red meats as well. When planning your full Arteflame menu, consider these pairings to create a cohesive dining experience:

• Welsh Lamb: The classic pairing. Grill lamb chops on the center grate and serve the sourdough on the side; the seaweed enhances the gaminess of the meat.
• Ribeye Steak: Place a pat of laverbread butter directly onto a searing hot steak while it rests. It acts as a natural seasoning sauce.
• Grilled Shellfish: Cockles, clams, or grilled prawns go hand-in-hand with laverbread. Use the buttered bread to sop up the shellfish juices.
• Poached Eggs: Use the grilled sourdough as a base for a Welsh-inspired Eggs Benedict or simply top with a soft poached egg for breakfast.

Conclusion

It bridges the gap between ancient foraging traditions and modern fire cooking, offering a taste profile that is both nostalgic and excitingly new for many palates.
