Iceland or Irish Moss Jelly

1 handful moss, washed in five waters, and soaked an hour.
1 quart boiling water.
2 lemons—the juice only.
1 glass of wine.
1/4 teaspoonful cinnamon. (Measure scantily.)

Soak the washed moss in a very little cold water; stir into the boiling, and simmer until it is dissolved. Sweeten, flavor, and strain into moulds. You may use two glasses of cider instead of one of wine for a fever-patient, putting in a little less water.

Good for colds, and very nourishing.

1 handful Irish or Iceland moss, washed in five waters.
2 quarts boiling water, poured upon the moss, and left until cold.
2 lemons, peeled and sliced, leaving out the peel.
Sweeten very well and ice.

Do not strain, and if it thicken too much, add cold water.

Excellent for feverish colds and all pulmonary troubles.

Moss Jelly

Steep Carragua, or Irish moss, in cold water a few minutes, to extract the bitter taste–then drain off the water, and to half an ounce of moss put a quart of fresh water, and a stick of cinnamon. Boil it till it becomes a thick jelly, then strain it, and season it to the taste with white wine and white sugar. This is very nourishing, and recommended highly for consumptive complaints.
