Identify how your recipe uses sweetened condensed milk (baking set, no-bake thickness, or frosting/filling texture).
Choose the closest function match from the table below, then start with the listed ratio.
If your substitute is thinner than expected (common with evaporated milk), simmer briefly or chill to thicken before using.
Taste and adjust: add a small pinch of salt for balance or a bit more sugar if the final dessert needs more sweetness.
For baked desserts, aim for a thick, spoon-coating consistency; for no-bake, prioritize chill time for proper set.
