🥄 Texture

Crunchy, butter-toasted bread gives a crisp outer shell while the fried eggs provide a tender, slightly runny center. Melted cheddar and mayo deliver a creamy, gooey mouthfeel that contrasts with the slight chew of the bread and the soft egg whites.

👃 Aroma

A strong savory/umami note from soy and melted cheddar is front and center, layered with warm butter/toast and a faint tomato vinegar tang. Hints of garlic and a whiff of red pepper flakes add subtle spice and complexity.

🍷 Pairs Well With

Crisp pilsner or a dry, slightly effervescent white wine (e.g., Sauvignon Blanc); nonalcoholic: iced green tea with lemon or sparkling water with a lemon wedge.

🥗 Side Dishes

Light mixed green salad with sesame or citrus dressing; quick pickled cucumbers or kimchi for contrast; or a side of kettle chips or sweet potato fries for additional crunch.

Ingredients(12 items)

12 slices bread (Italian-style, cut diagonally)

23 tablespoons mayonnaise

32 large eggs

41 cup shredded cheddar cheese (divided: 1/2 cup for filling, 1/2 cup for topping)

53 tablespoons soy sauce

62 tablespoons rice vinegar

72 tablespoons tomato flakes (rehydrated with 2 tablespoons water)

81 tablespoon butter (for pan-frying eggs)

91 teaspoon salt

101/2 teaspoon black pepper

111/2 teaspoon garlic powder (optional enhancement)

121/4 teaspoon red pepper flakes (Thai-Korean influence)

Instructions

Prepare the Umami Sauce: In a small bowl, whisk together 3 tablespoons soy sauce, 2 tablespoons rice vinegar, and 2 tablespoons rehydrated tomato flakes (mix tomato flakes with 2 tablespoons water and let sit for 2 minutes). Set aside.

Create Fusion Mayo: Mix 3 tablespoons mayonnaise with 1/2 teaspoon of the umami sauce and 1/4 teaspoon red pepper flakes. Stir until well combined.

Toast the Bread: Heat a skillet or griddle over medium-high heat. Lightly butter both sides of the bread slices and toast until golden brown and crispy (approximately 2-3 minutes per side). Set toasted bread aside on a plate.

Fry the Eggs: In the same skillet, melt 1 tablespoon butter over medium heat. Crack both eggs into the pan and fry until the whites are set but yolks remain slightly runny (sunny-side up style, approximately 3-4 minutes). Season eggs with salt and pepper.

Assemble the Base: Spread the fusion mayo evenly on both toasted bread slices.

Layer the Fillings: On the bottom bread slice, place 1/2 cup shredded cheddar cheese, then carefully transfer both fried eggs on top of the cheese.

Add Top Layer: Sprinkle remaining 1/2 cup cheddar cheese over the eggs, then place the second bread slice on top (mayo-side down).

Final Sauce Application: Drizzle 1-2 tablespoons of the remaining umami sauce over the top of the sandwich for added depth and complexity.

Optional Panini Press: For an authentic Italian-fusion touch, place the assembled sandwich in a panini press or skillet (weighted with a plate) for 1-2 minutes to melt the cheese and bind all flavors together.

Serve immediately while warm, with extra umami sauce on the side for dipping.
