Directions

<ol class="no-list-style"><li class="MethodStepper"><h4 class="step-title">Step 1: Prepare the Koji-Aged Butter (48 hours ahead)</h4>Bring butter to room temperature until malleable but not melted. Mix the butter with shio koji paste until thoroughly combined. Shape into a rectangle, wrap tightly in parchment paper, and refrigerate for 48 hours. This fermentation process breaks down the butter's proteins and fats, creating complex umami flavors and making the butter more pliable for lamination.</li><li class="MethodStepper"><h4 class="step-title">Step 2: Make the Croissant Dough</h4>In a stand mixer fitted with a dough hook, combine flour, sugar, salt, and yeast. Slowly add cold milk while mixing on low speed. Once incorporated, increase to medium speed and mix for 3 minutes. Add the softened butter and continue mixing for another 2 minutes until you have a smooth, elastic dough. Shape into a rectangle about 2cm thick, wrap in plastic, and refrigerate for at least 2 hours or overnight. The cold fermentation develops flavor and gluten structure.</li><li class="MethodStepper"><h4 class="step-title">Step 3: Laminate the Dough</h4>Remove the koji-aged butter from the refrigerator 15 minutes before use - it should be cool but pliable. On a lightly floured surface, roll the dough into a rectangle twice as long as the butter block. Place the butter in the center and fold the dough over it like an envelope. Seal the edges by pinching. Turn the dough 90 degrees and roll it out to a 45cm x 20cm rectangle. Fold it in thirds like a letter. This is your first turn. Wrap and refrigerate for 1 hour to relax the gluten and keep the butter cold.</li><li class="MethodStepper"><h4 class="step-title">Step 4: Complete the Lamination</h4>Perform two more turns as in Step 3, chilling the dough for 1 hour between each turn. After the final turn, wrap the dough and refrigerate for at least 2 hours or overnight. This careful lamination process creates the delicate layers that will puff and separate during baking.</li><li class="MethodStepper"><h4 class="step-title">Step 5: Prepare the Lobster Filling</h4>In a medium bowl, gently combine the chopped lobster meat, mayonnaise, chives, tarragon, lemon zest, 1 tablespoon of lemon juice, and Dijon mustard. Season with salt and pepper to taste. Refrigerate until ready to use. The acidity of the lemon brightens the rich lobster while the herbs add freshness to balance the buttery pastry.</li><li class="MethodStepper"><h4 class="step-title">Step 6: Shape the Wraps</h4>Roll the laminated dough on a lightly floured surface into a large rectangle approximately 60cm x 30cm and 3mm thick. Using a sharp knife or pizza cutter, cut the dough into 10 equal squares. Place about 2 tablespoons of lobster filling in the center of each square. Brush the edges with egg wash, then fold the corners toward the center, overlapping slightly to create a wrap. Press gently to seal. Transfer to parchment-lined baking sheets, leaving space between each wrap.</li><li class="MethodStepper"><h4 class="step-title">Step 7: Final Proof and Bake</h4>Let the wraps proof at room temperature for 1-1.5 hours until slightly puffy. Meanwhile, preheat your oven to 200°C. Brush the wraps with egg wash and sprinkle with flaky sea salt. Bake for 20-25 minutes, rotating the pans halfway through, until deeply golden brown and crisp. The internal temperature should reach 88°C. Allow to cool for 10 minutes before serving – the pastry needs this time to set its structure and complete the cooking process of the inner layers.</li><li class="MethodStepper"><h4 class="step-title">Step 8: Serve</h4>These wraps are best enjoyed warm, when the contrast between the crisp exterior and tender interior is most pronounced. If desired, serve with additional lemon wedges or a small dish of tarragon-infused mayonnaise for dipping. These can be made ahead and reheated in a 180°C oven for 5-7 minutes if needed, though they're at their absolute flakiest when fresh.</li></ol>

FAQs

What ingredients are used in Koji-Aged Butter Croissant Dough Lobster Wraps?

These luxurious wraps require high-quality European butter, shio koji paste, bread flour, fresh yeast, milk, cooked lobster meat, fresh herbs (chives and tarragon), lemon, Dijon mustard, mayonnaise, and flaky sea salt for finishing.

How to cook Koji-Aged Butter Croissant Dough Lobster Wraps at home?

Learn how to cook Koji-Aged Butter Croissant Dough Lobster Wraps by first fermenting butter with koji for 48 hours, then creating laminated dough through a series of folds. After preparing a herb-infused lobster filling, shape the dough into squares, add filling, fold into wraps, and bake until golden brown. The process combines French pastry techniques with Japanese fermentation for an elegant result.

What does koji aging do to butter in pastry recipes?

Koji aging breaks down the butter's proteins and fats through enzymatic action, creating complex umami flavours and a more pliable texture. This makes the butter easier to work with during lamination while adding depth of flavour to the finished pastry that regular butter cannot achieve.

Can I make components of these lobster wraps ahead of time?

Yes! The koji-aged butter can be prepared 3-5 days in advance. The croissant dough can be made and laminated 1-2 days ahead and kept refrigerated. The lobster filling can be prepared up to 24 hours before assembly. Fully baked wraps can be frozen for up to 1 month.

What are good substitutes for lobster in these gourmet wraps?

Excellent substitutes include crab meat, poached prawns, or smoked salmon for seafood options. For non-seafood alternatives, try roasted mushrooms with thyme, caramelised leeks with gruyère cheese, or a mixture of ricotta with fresh herbs and lemon zest for a vegetarian version.
