Hi Alison, I have never tried using honey.... interesting idea.
I'm sure you know this, but they taste very different than refined sugar, especially if your not use to them. And they will make anything you use them in -taste very different-
Amount for amount you can swap rapadura for white sugar, but you may want to taste test your mix in case you decide to ease up on the darker sweetener in the beginning until you get used to the new taste combinations. Or even go half 'n half in the beginning.
However honey is always it's own special deal. So I would recommend you use a honey-jam recipe (Google it) and not try swapping it out on your own until you have some
experience in this area under your belt. Sorry I cannot add any personal experience in this case, let us know how it turns out.....
Article I have from Mother Earth News:
If you prepare jams and jellies with natural sweetening, you should remember that the moisture content of honey varies according to location. In California, for example, sweets made with honey from the northern part of the state will be softer than the same products made with the output of bees kept farther south.
I hope these recipes will be of value to readers who love sweets but want to avoid refined sugar. Enjoy!
PEAR AND CHERRY CONSERVE
2-1/2 to 3 pounds fully ripened Bartlett pears
6 lemon slices
3 Tbs. seedless golden raisins
1/4 cup maraschino cherries, chopped
1/3 cup maraschino cherry juice
4 cups mild-flavored honey
1 bottle liquid pectin
Peel, core and coarsely chop the pears. (There should be 5 cups.) Cut the lemon slices into eighths. In a 6—8-quart saucepan, mix together all the ingredients except the pectin. Bring them to a full rolling boil, stirring constantly, and boil them hard for 5 minutes. (Give the mixture an occasional turn with a spoon to prevent scorching.) Remove the pan from the heat and at once blend in the liquid pectin. Skim off the foam with a metal spoon, and continue to stir and skim for 5 minutes to prevent the fruit from floating. Ladle the conserve into hot sterilized jars and seal the containers. This recipe makes about seven half-pint glasses.
HONEY PINEAPPLE JAM
2-1/2 cups (1-pound 4-1/2-ounce can) crushed pineapple
