Irish Moss Blanc-Mange

Ingredients

Directions

Prepare the moss

  1. Soak the Irish moss in cold water for 15 minutes.

  2. Pick over and wash the moss, then tie it in a lace bag.

Make the blanc-mange

  1. Place the bag in a double boiler with the milk.

  2. Boil until the milk thickens when dropped on a cool plate.

  3. Add the salt, then strain and flavor with vanilla.

Mould and serve

  1. Mould the mixture in small cups or egg-shells.

  2. To prepare egg-shells, break off a piece as large as a ten-cent piece, pour out the egg, rinse the shells, and stand them upright in a pan of meal.

  3. Fill the shells with the blanc-mange.

  4. Serve with sugar and cream, or with apple or grape jelly, or place half a peach or any candied fruit in the bottom of the cup before filling.

What each ingredient does

Irish moss
Seaweed that releases gelling agents into the milk, setting it into a firm, jelly-like body.
Milk
Forms the main body of the dessert, and its proteins help give the set custard a creamy texture.

The step that matters

Boil until the milk thickens when dropped on a cool plate. Irish moss gels as it is simmered, so the mixture must be cooked long enough to extract its setting power. Stop too early and the blanc-mange will stay loose; the cool-plate test checks the set before moulding.
