Replacing white sugar with brown sugar is only a relative improvement. Whole or raw sugar (evaporated juice from cane sugar) would be a better substitute, but its strong flavor often masks the taste of the fruit. For so-called "sugar-free" recipes, you can instead add: • Honey. The measurements are as follows: 2 volumes of sugar equals 1 volume of honey. You will need to cook the jam a little longer than the time indicated in the recipe using sugar. The consistency of the jam or jelly will be a little runnier. • Other natural sweeteners such as Stevia, Norbu, or even Xylitol. We will only put 3 tablespoons instead of 1 cup of sugar used in the traditional jam recipe.
