Diplomatic Pudding

Ingredients

Directions

Prepare

  1. Melt the lemon jelly in warm water.

  2. Cover the gelatine with milk and dissolve it over low heat; keep warm.

  3. Beat the egg yolks with sugar, add the remaining milk, and stir over heat until thickened.

  4. Flavour with a few drops of almond essence and mix with the dissolved gelatine.

  5. Crumble the ratafias and slice the sponge cakes; pour the custard over them and let soak.

Assemble and set

  1. Wet a mould and run a little lemon jelly over the bottom and sides; let it set.

  2. Blanch the pistachio nuts in boiling water, peel, and chop finely.

  3. Arrange the chopped nuts around the bottom of the mould, using a little jelly to secure them.

  4. When the last layer of jelly is still, pour the soaked cakes into the mould.

  5. Set in a cool place until the next day.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Egg yolks
Thicken the milk custard and add richness and a smooth set texture.
Gelatine
Sets the custard so the pudding holds its shape when turned out.
Sponge cakes
Soak up the custard to give the pudding a soft, cake-based body.
Milk
Forms the liquid base of the custard, adding creaminess and moisture.
Lemon jelly
Adds a bright, sweet-tart flavour and a set layer to the mould.

The step that matters

Thickening the custard. Egg yolks set when heated, so stirring over gentle heat until thickened, without boiling, prevents curdling and keeps the custard smooth before it is mixed with the gelatine.
