Japanese Omuraisu: Omurice and the Yoshoku Egg Architecture

Ingredients

• For the kecharaisu
• 600 g day-old cooked short-grain rice, cold, dry — not freshly cooked
• 200 g boneless chicken thigh, cut into small dice
• 1 medium yellow onion, finely diced
• 60 g tomato ketchup
• 30 g unsalted butter
• 1 tsp fine salt
• ½ tsp ground white pepper
• For the omelette (per portion — Kyoto flap-open style)
• 3 eggs, beaten
• 1 tsp double cream, added to beaten eggs
• 15 g unsalted butter, generous quantity for the pan
• For the sauce
• 200 ml demi-glace, made from proper veal or chicken stock reduction; instant demi-glace is acceptable

Method

1. 1
   Melt the butter for the kecharaisu in a wide, heavy pan over medium-high heat. Add the diced onion and sauté, stirring frequently, until softened and beginning to colour at the edges. Add the diced chicken and cook, stirring, until the pieces are cooked through and any released moisture has evaporated — the pan should sound dry and the chicken should show light colour.
2. 2
   Add the cold day-old rice to the pan, breaking up any clumps. Stir-fry at medium-high heat, pressing and turning the rice, until each grain is separate and the rice is heated through with no steam rising — the pan must sound consistently hot and crackling rather than wet.
3. 3
   Add the ketchup directly to the rice. Stir constantly at medium-high heat for 30 to 45 seconds until the ketchup is fully incorporated and its raw acidity has mellowed into the rice — the colour should be even and the sharp tomato smell should soften to a rounded, cooked sweetness. Season with salt and white pepper. Keep the kecharaisu warm while the omelettes are made.
4. 4
   This is where the dish lives or dies. For the Kyoto flap-open style: beat 3 eggs with 1 teaspoon of cream for one portion. Melt 15 g of butter in a small, well-seasoned or non-stick pan over medium-high heat until foaming. Pour in the egg mixture and stir gently with a spatula, drawing the edges to the centre. Remove the pan from the heat while the eggs are still visibly loose and molten at the centre — the residual heat will continue the cook. The egg must not be set through: the flowing interior is the entire point of this style. Work quickly.
5. 5
   Mound one portion of the warm kecharaisu on a plate, shaping it into a compact oval football form. Slide or lift the barely-set omelette from the pan onto the centre of the rice mound. Score the top of the omelette with a single lengthwise cut and allow the molten interior to open and flow over the rice. The egg should pour rather than hold its shape — if it holds firm, the omelette was cooked too long.
6. 6
   Spoon the warmed demi-glace over or alongside the opened omelette. Serve immediately — the egg continues to set on the plate and the dish waits for no one.
