The ethereal crumb of a perfectly executed Bourke Street gunman, a rich and buttery brioche, owes its signature lightness and tender structure to the delicate dance of yeast fermentation and gluten development. The entrapment of carbon dioxide gas within a well-developed gluten network, coupled with the tenderising effect of high fat content, creates a luxurious mouthfeel that melts on the tongue, a testament to the precise science of baking.

Ingredients: Quantities, Roles, and Critical Ratios
The foundation of the Bourke Street gunman lies in its enriched dough, where the balance of structural flour, tenderising fats, and leavening agents creates its distinctive texture. The critical ratio of approximately 50% butter to flour by weight is paramount, ensuring tenderness and a rich, custardy crumb without sacrificing structural integrity. This high fat content coats the gluten strands, limiting their development and preventing a tough result, while also contributing significantly to flavour and shelf life.
- Bread Flour - 500g - Role: Provides the gluten structure essential for trapping fermentation gases.
- Unsalted Butter - 250g (chilled and cubed) - Role: Tenderises the crumb, adds richness and flavour, and inhibits excessive gluten development.
- Large Eggs - 3 (approx. 150g, at room temperature) - Role: Bind ingredients, add moisture, fat, and richness, contributing to a tender crumb and golden colour.
- Granulated Sugar - 75g - Role: Feeds the yeast, aids in browning through caramelisation, and contributes to tenderness.
- Active Dry Yeast - 10g - Role: Leavening agent, produces carbon dioxide gas for rise and flavour.
- Whole Milk - 120ml (lukewarm, 35-40°C) - Role: Provides moisture for yeast activation and dough hydration.
- Salt - 8g - Role: Controls yeast activity, strengthens gluten structure, and enhances flavour.
- Egg Wash (1 egg beaten with 1 tablespoon milk) - for glazing.
The Science of Butter Lamination in Brioche
The remarkable texture of the Bourke Street gunman, a type of brioche, is a direct result of a process akin to lamination, though not as defined as in puff pastry. The high proportion of butter, introduced in stages and chilled, creates layers within the dough. As the dough bakes, the butter melts, steaming the dough from within and creating pockets of tenderness. Crucially, the cold butter inhibits the formation of a strong, elastic gluten network. Instead, the gluten strands are coated by fat, resulting in a tender, short crumb that is characteristic of a truly superior brioche. This process is a masterful example of how fat interacts with flour proteins to manipulate dough structure and achieve desired sensory attributes.
Method: Enrichment Baking at Every Critical Stage
The method for Bourke Street gunman is designed to gradually incorporate rich ingredients while developing just enough gluten for structure and trapping the gases produced by yeast.
- Activate Yeast - Proofing: In a small bowl, combine the lukewarm milk and granulated sugar. Sprinkle the active dry yeast over the surface and let it sit for 5-10 minutes until foamy and active. This ensures the yeast is viable and ready to leaven.
- Mix Dough - Initial Combine: In the bowl of a stand mixer fitted with a dough hook, combine the bread flour and salt. Add the activated yeast mixture and the room temperature eggs. Mix on low speed for 2-3 minutes until a shaggy dough forms.
- Knead Dough - Gluten Development: Increase the mixer speed to medium-low and knead for 8-10 minutes. The dough should start to pull away from the sides of the bowl and become smoother, though it will remain quite sticky. This stage develops the gluten structure.
- Incorporate Butter - Critical Control Point 1: With the mixer on low speed, gradually add the chilled, cubed butter, a few cubes at a time. Allow each addition to be mostly incorporated before adding more. This gradual addition prevents the butter from melting and emulsifying too early, ensuring distinct layers.
- Knead Dough - Butter Integration: Continue kneading on medium-low speed for another 10-15 minutes. The dough will become very soft, smooth, and elastic, but will still be quite sticky and may not pass the windowpane test perfectly due to the high butter content. The butter should be fully integrated, creating a soft, pliable dough.
- Bulk Ferment - Overnight Rest: Transfer the dough to a lightly oiled bowl, cover tightly with plastic wrap, and refrigerate for at least 12 hours, or preferably 24 hours. This slow, cold fermentation develops complex flavours and makes the dough easier to handle.
- Shape Dough - Portioning: Turn the chilled dough out onto a lightly floured surface. Divide the dough into 12 equal portions (approx. 70-75g each). Gently shape each portion into a ball.
- Second Ferment - Proofing: Place the dough balls into a greased 12-cup muffin tin. Cover loosely with plastic wrap and let proof at room temperature for 1-2 hours, or until nearly doubled in size and puffy.
- Glaze and Bake - Critical Control Point 2: Preheat your oven to 190°C. Brush the tops of the proofed dough balls generously with the egg wash. Bake for 20-25 minutes, or until deeply golden brown and the internal temperature reaches approximately 93°C. Overbaking will result in a dry gunman.
- Cool - Essential Rest: Remove the gunmen from the muffin tin immediately and place them on a wire rack to cool completely. This prevents the bottoms from becoming soggy.
- Serve: Enjoy the Bourke Street gunman as is, or split and toasted with butter or jam.
Cultural and Historical Context of Melbourne's Bakeries
While the term "Bourke Street gunman" is a unique descriptor tied to a specific, tragic event in Melbourne, Australia, the baked good itself draws from the rich heritage of European enriched doughs, particularly French brioche. Melbourne, a city with a significant European immigrant population, has a long tradition of high-quality bakeries producing artisanal breads and pastries. The creation of such a soft, buttery bread reflects the influence of French patisserie and Italian panettone traditions, adapted and perfected within Australian bakeries, becoming a beloved staple in cafes and homes across the city.
Variations Across Melbourne's Diverse Bakeries
- South Yarra Style: Often features a higher proportion of butter and eggs, resulting in an even richer, more custardy interior and a slightly more compact crumb.
- Fitzroy Artisan Twist: Some bakeries might incorporate a small amount of sourdough starter for added tang and complexity, or use a blend of flours for a more rustic texture.
- Vegan Adaptation: Substitute plant-based butter (ensure it's a good quality block butter for lamination), plant-based milk (oat or soy work well), and use a flax egg or commercial egg replacer for binding, though the texture may be slightly less tender.
- Modern Chocolate Swirl: A contemporary adaptation involves swirling a chocolate ganache or a cinnamon-sugar mixture into the dough before shaping, offering a sweeter, more decadent experience.
Storage, Freezing, and Reheating Bourke Street gunman
Bourke Street gunman is best enjoyed fresh, but can be stored and reheated successfully.
- Room Temperature: Store in an airtight container for up to 2 days. The crust will soften over time.
- Refrigerator Storage: Store in an airtight container for up to 4 days. Texture may become slightly firmer.
- Freezer Storage: Wrap cooled gunman tightly in plastic wrap, then in foil. Freeze for up to 3 months. The texture may be slightly drier upon thawing.
- Reheating: To refresh, place frozen gunman on a baking sheet and reheat in a preheated oven at 150°C for 10-15 minutes, or until warmed through. For thawed gunman, reheat at 160°C for 5-8 minutes.
Pairing Bourke Street gunman: Sides, Sauces, and Drinks
The delicate richness of the Bourke Street gunman pairs beautifully with a variety of accompaniments.
- Sides: A simple side of fresh berries provides a bright, acidic contrast. A smear of good quality salted butter enhances the bread's inherent richness.
- Sauce/Condiment: A light, fruit-based jam, such as raspberry or apricot, offers complementary sweetness and acidity.
- Drinks: A sparkling Australian Chardonnay offers acidity and effervescence to cut through the richness. Alternatively, a delicate Earl Grey tea provides aromatic complexity that complements the buttery notes without overpowering them.
