This is the original version of Knox Gelatine's famous candy. The new, updated version calls for 5 envelopes Knox unflavored gelatin. Knox Gelatine still gets many requests for this recipe.
4 envelopes Knox unflavored gelatin
1 cup cold water
1 1/2 cups boiling water
4 cups granulated sugar
1/4 teaspoon salt
Red and green food coloring (optional)
1 teaspoon cinnamon extract (not powder)*
1/2 teaspoon peppermint extract*
Heat sugar, salt and boiling water to boiling point. Soften gelatin in cold water. Add to hot syrup and stir until dissolved. Boil slowly for 15 minutes.
Remove from fire and divide into two equal parts. Color one part a delicate red and flavor with cinnamon extract; color the other part a delicate green and flavor with peppermint extract.
Rinse two pans (about 8 x 4 inches) in cold water, and pour in candy mixture to the depth of about three-fourths inch and put in a cool place (not a refrigerator), allowing candy to thicken for at least twelve hours.
With a wet sharp knife, loosen around edges of pan, put out on board lightly covered with confectioners' sugar. Cut into cubes and roll in confectioners' or fine granulated sugar.
* You can also use 10 drops oil of cinnamon. Or substitute lemon: add 3 tablespoons lemon juice and 2 teaspoons lemon extract to one part of the candy and leave it uncolored or tine pale yellow. You also can substitute 1/2 teaspoon strawberry extract for either the cinnamon or the peppermint. Other flavor suggestions include using 2 teaspoons coconut extract.
