Can you use sweetend condensed milk and not add the sugar for recipe?

You can absolutely use sweetened condensed milk in a recipe and omit the sugar! Sweetened condensed milk is already very sweet, so adding additional sugar would likely make the recipe overly sweet.

Here are a few things to keep in mind when using sweetened condensed milk without extra sugar:

* Taste the recipe: Before adding any extra sugar, taste the recipe to assess the sweetness level. You might find that the sweetness is just right as is.

* Adjust other ingredients: If you feel the recipe needs a bit more sweetness, you might try balancing it with a touch of sourness (like lemon juice or vinegar) or adding other complementary flavors that will enhance the taste.

* Consider the recipe's intended sweetness: Some recipes, like caramel sauce or sweet treats, are expected to be very sweet. If you're making one of these, you might want to add a small amount of sugar even though you're using sweetened condensed milk.
