Irish Moss Blanc-Mange

Ingredients

Directions

Prepare the moss and milk

  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.

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

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

Flavor and mould

  1. Add the salt, strain, and flavor with vanilla.

  2. Mould the mixture in small cups or egg‑shells.

  3. 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.

  4. Fill the shells with the blanc‑mange.

Serve

  1. 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
Its natural gel-forming compounds thicken the milk as it simmers, setting the dessert.
Milk
Forms the liquid base that the moss thickens into a creamy, smooth set.

The step that matters

Boil until the milk thickens when dropped on a cool plate. Irish moss gels only when its thickening compounds are fully extracted by sustained gentle heat. Stopping too early leaves the mixture runny, while overcooking can make it stiff or grainy. The drop test on a cool plate shows when it is ready to set.
