Converting Liquid Sweeteners Without Breaking the Recipe
Liquid sweeteners are not a one-for-one swap for sugar. They carry water, they brown at
different rates, and some of them pull a recipe’s acid and soda balance out of line.
The rows below are the substitution rules published by Colorado State University Extension,
written in the direction a recipe question usually arrives: the recipe calls for one cup of
this sweetener, so what do I use instead.
Sweetener-to-sugar conversions (Colorado State University Extension).
| Called for | Replace with | Adjust the rest of the recipe |
| Honey, 1 cup | 1 1/4 cups sugar | Add 1/4 cup of the liquid already in the recipe. |
| Corn syrup, 1 cup | 1 cup granulated sugar, or 1 cup honey | With the sugar, add 1/4 cup of the liquid in the recipe. |
| Maple syrup | 2 cups sugar plus 1 cup water, boiled clear, then 1/2 tsp maple
flavouring | None — the water is already in the substitute. |
| Molasses, 1 cup | 3/4 cup sugar | Increase liquid by 5 tbsp, drop the baking soda by 1/2 tsp, and add 2 tsp
baking powder. |
| Brown sugar, 1 cup | 1 cup granulated sugar, or 1 cup granulated plus 1/4 cup unsulphured
molasses | Nothing, unless you build it from molasses, which brings its own acid. |
Sweeteners differ in calories as much as in sweetness
The calorie-per-gram figures below come from Utah State University Extension’s
comparison of frequently used sweeteners. Note what they say about the natural liquids: a
gram of honey, agave or maple syrup carries 3 calories against the 4 in table sugar, while
the high-intensity sweeteners contribute none.
Calories per gram and suitability for home canning (Utah State University Extension).
| Sweetener | Calories per gram | Listed as suitable for canning |
| Sucrose (table sugar) | 4 | Yes |
| Light corn syrup | 4 | Yes |
| Honey | 3 | Yes |
| Agave | 3 | No |
| Maple syrup | 3 | No |
| Stevia | 0 | Only in jams and jellies made with no-sugar pectin |
| Monk fruit | 0 | No |
That third column matters more than the second if you preserve food. A sweetener can be
perfectly safe to bake with and still not be a safe substitute in a jar, because sugar also
controls water activity in preserved fruit and jam. Of the natural liquid sweeteners, only
honey is listed as suitable for canning; agave and maple syrup are not.
What the label means by “substitute”
The Food and Drug Administration regulates high-intensity sweeteners as food additives
unless their use as a sweetener is generally recognized as safe, the GRAS class that stevia
and monk fruit sit in. That is why they reach the shelf without a premarket approval step.
Two consequences follow for cooking. They are many times sweeter than table sugar, so a
fraction of a spoon replaces a cup, and they contribute few or no calories and generally do
not raise blood sugar. The calculator above converts sweetness; it does not restore the
volume or the browning that the sugar itself was providing.
The Dietary Guidelines for Americans count liquid sweeteners as added sugars — honey,
agave syrup, corn syrup and molasses are all named in the added-sugar list, and the guidance
caps a meal at 10 grams. Swapping one liquid for another changes the flavour and the water
balance, not the classification.
One safety rule that overrides taste
Do not feed honey to a child younger than 1 year. Honey can contain the spores that cause
infant botulism, and the warning covers honey as an ingredient and products made with it.
For a baby’s food, use a different sweetener or none at all.
