Converting 3/4 cup into 1.5 sticks is straightforward, but the composition of those sticks changes depending on whether they contain salt. In the debate over unsalted vs salted butter, bakers must weigh water content alongside salinity.
Unsalted butter provides pure sweet cream flavor with zero added sodium, keeping moisture levels around 16% to 18%. Salted butter contains approximately 1.5% to 2% added table salt by weight. In an amount as large as 3/4 cup (170 grams), using salted butter adds roughly 2.5 to 3.4 grams of pure salt, equivalent to over half a teaspoon of fine table salt.
If a recipe already includes separate salt measurements, using 1.5 sticks of salted butter can push the final bake into overly savory territory. More crucially, salt acts as a preservative that can vary wildly by dairy brand. Land O'Lakes salted butter averages about 90 milligrams of sodium per tablespoon, while regional store brands can register significantly higher. Unsalted butter removes this variable, granting absolute control over flavor and structural chemistry.
