Baking Mistake Alert: Exactly How Many Cups Is 3/4 Stick of Butter?
Selecting unsalted versus salted butter also alters the chemistry of the recipe. The baseline unsalted vs salted butter ratio runs fairly consistent across major dairy producers: salted varieties contain roughly 1/4 teaspoon (1.5 grams) of dissolved salt per stick. A 3/4 stick portion of salted butter incorporates approximately 3/16 teaspoon (1.1 grams) of sodium chloride.
If you swap salted butter into a recipe requesting unsalted, reduce added table salt by just under a quarter-teaspoon. Neglecting this tweak sharpens the crust flavor uncomfortably, overpowering delicate brown butter or vanilla undertones.
When swapping for butter substitution equivalents, such as vegetable shortening, lard, or vegan baking blocks, account for moisture content. Pure vegetable shortening contains zero water, whereas standard American butter averages 16% to 18% water and 80% to 82% milkfat. When replacing 3/4 stick of butter (85 grams) with shortening, use 70 grams of shortening and add roughly 1 tablespoon (15 milliliters) of cold milk or water to match the lost dairy moisture.
