Gochujang Umami Burger

Inspired by the cult-favorite burger joint Franky’s in Stockholm, this burger redefines indulgence with an unapologetic collision of earthy luxury and savory punch. A hard-smashed beef patty with deeply caramelized, lacy edges is blanketed in molten sharp cheddar, layered with shaved crisp white onion, and balanced by briny dill pickles. What elevates it into modern bistro territory is the sauce interplay: rich, velvet truffle mayonnaise tucked beneath a glossy, spicy-sweet gochujang-miso reduction.

Ingredients

The Umami Sauces

• 0.25 cup high-quality mayonnaise
• 2 tsp black truffle paste or minced truffle carpaccio
• 1 tbsp gochujang paste
• 1 tbsp mild white or yellow miso paste
• 1 tbsp mirin (or honey)

The Beef & Assembly

• 1.5 lb fresh ground beef chuck (80/20), divided into 4 balls
• 4 pieces brioche or potato burger buns, split
• 4 pieces thick deli-cut sharp cheddar slices
• 0.5 pieces white onion, shaved paper-thin on a mandoline
• 12 pieces thinly sliced dill pickle chips
• 2 tbsp unsalted butter, softened
• Coarse kosher salt & cracked black pepper, to taste

Instructions

1. 1
   Fold Truffle Mayo

   Whisk mayonnaise and truffle paste until glossy and homogenous. Cover and refrigerate to allow flavors to meld.

2. 2
   Simmer Umami Glaze

   Whisk gochujang, miso, mirin, and warm water in a small pan over low heat until silkily reduced. Keep warm.

3. 3
   Toast Buns

   Spread softened butter across bun faces. Griddle on medium heat until burnished mahogany and crisp; set aside.

4. 4
   Hard Smash Patties

   Set cast iron to smoking high. Drop beef, press flat with parchment, season aggressively, and sear until deeply lacquered.

5. 5
   Melt Cheddar

   Scrape up crisp fond, flip patty, top immediately with cheddar, and tent with a lid for 30 seconds.

6. 6
   Plate the Burger

   Smear truffle mayo on heels. Top with pickles, shaved onion, cheesy patty, generous warm gochujang glaze, and bun caps.

The Chef's Secret

Never use cheap truffle oil—its synthetic perfume overwhelms the delicate balance. Genuine black truffle carpaccio or paste binds naturally with the egg emulsion in mayonnaise, creating a buttery baseline that softens the sharp fermented punch of the gochujang and miso.

Sommelier Pairing

Northern Rhône Syrah (Crozes-Hermitage): The savory tapenade, black pepper, and dark fruit notes cut right through the rich truffle mayo, while moderate tannins cleanly reset the palate against the fermented chili glaze.
