Steamed Egg Custard with Blue Crab and Flowering Chives

This elegant steamed egg custard with blue crab and flowering chives is a sophisticated dish that celebrates delicate textures and refined Japanese-inspired flavours. The base of the custard is a homemade dashi, infused with dried mushrooms and kombu, which provides a deep umami foundation without the need for heavy fats. It is a wonderfully silky, savoury custard that balances the sweetness of jumbo lump crabmeat with the gentle onion notes of fresh Chinese chives.

As a diabetes-friendly recipe, this dish is naturally low in carbohydrates and high in high-quality protein, making it an excellent choice for a nutritious light lunch or an impressive dinner party starter. The use of traditional steaming techniques ensures the custard remains light and wobbly, while the fresh seafood topping adds a touch of luxury to every spoonful. Serve immediately while warm to enjoy the fragrance of the sesame oil and sherry.

How to make Steamed Egg Custard with Blue Crab and Flowering Chives

Simmer mushrooms in water in a small saucepan 5 minutes, then let steep off heat 10 minutes. Add kombu and return just to a simmer. Turn off heat and add bonito flakes, then let steep 10 minutes. Strain stock through a fine-mesh sieve into a bowl or glass measure, discarding solids. Cool dashi to room temperature.

Beat eggs and 350ml cooled dashi in a medium bowl, then whisk in remaining custard ingredients.

Divide among bowls. Cover each tightly with foil and arrange in a steamer rack. Steam, covered, over simmering water until just barely set in centre, 8 to 10 minutes. Remove pot from heat and let stand, covered, 2 to 3 minutes. (Custard will continue to set.)

Blanch chives in a medium pot of boiling salted water 30 seconds, then transfer to an ice bath to stop cooking. Pat chives dry. Cut into 3/4-inch pieces and gently combine with crab and remaining ingredients.

Top warm custards with crab mixture.
