Aren't serving sizes funny. I would read this recipe as 2500 cals a serving
Recently I bought a small jar of cocktail sause that said it had 35 serving?!?
For who? Kebler elves.
Cfmama-
You can absolutely sub out/ eliminate the sugar.
The only time it gets a bit tricky is with baked goods like cake, etc.
in my kitchen, I would omit the sugar all together, keep the honey, maybe increase by a tblspn, add a bit of molassas for that 'brown sugar' flavor, add some water if the mixture needed to be wetter before baking
