Decide your use case: baking (cookies/cakes) needs moisture-like brown sugar, while sauces/glazes can handle liquid sweeteners.
Start with the listed ratio: use the 1:1 options for closest behavior, or the ¾:1 maple blend for liquid-based swaps.
If your substitute is drier (demerara/turbinado), increase resting or add a splash of moisture from the recipe (e.g., butter/eggs) to prevent overly crisp results.
If your substitute is liquid (maple), reduce any added liquids by a small amount and watch browning—liquid sugars can darken faster.
Taste-test the mix (or do a quick test batch) and adjust: add a pinch of salt/acid balance for richer molasses flavor.
