Silken Citrus Custard with Herb Oil

Headnote

This dish is built from restraint: a soft custard set to a delicate tremor, brightened by citrus and finished with a precise herbal oil. Its value lies in contrast, where richness is held in check by freshness and the plate remains lucid rather than heavy. The result should be smooth, clean, and composed, with each element distinct yet inseparable.

Ingredients

Custard

60 g milk

20 g cream

10 g egg yolk

5 g whole egg

3 g citrus juice

1 g citrus zest

1 g salt

Herb oil

0.5 g fresh herb leaves

0.5 g neutral oil

Method

1. Preheat the oven to 150°C. Set the ramekin in a baking tray and bring a kettle of water to a simmer for the bain-marie.

2. Combine the milk, cream, citrus juice, citrus zest, and salt in the saucepan. Warm over low heat for 3 to 4 minutes, just until steaming and fragrant; do not allow it to boil.

3. In the heatproof bowl, whisk the egg yolk and whole egg until smooth and unified, without incorporating excess air.

4. Whisk the hot dairy into the eggs in a thin stream. Return the mixture to the saucepan and cook over low heat, stirring constantly with the whisk, for 2 to 3 minutes until the custard lightly coats the whisk and reaches 78°C to 82°C.

5. Strain the custard through the fine-mesh sieve into the ramekin. The surface should be perfectly smooth and free of bubbles.

6. Pour hot water into the baking tray to come halfway up the sides of the ramekin. Bake for 12 to 15 minutes, until the custard is just set at the edges and still trembles at the center.

7. Remove the ramekin from the water bath and rest for 5 minutes. The custard should settle into a soft, satin finish.

8. Blend the herb leaves with the neutral oil until vividly green and smooth. Pass if necessary for absolute refinement.

9. Spoon or dot the herb oil over the custard in a controlled pattern.

Plating and serving

Serve the custard warm in its ramekin or unmolded onto a small chilled plate. The surface should remain glossy, with the herb oil providing a restrained green accent rather than a heavy garnish. The final impression must be tender, clean, and precise.

Professional notes

The custard must never boil; heat control determines its silkiness.

Straining is not optional. It ensures the finished texture is fine and disciplined.

Bake only to a gentle wobble. Overbaking will turn the custard grainy and dull.
