Salted vs unsalted butter
The difference is control, not quality — and it matters far more in some bakes than the internet suggests.
The short answer
Use whichever you have for most baking and adjust the added salt if you care. The reason recipes specify unsalted is control rather than superiority: salt levels differ substantially between brands, so a recipe that assumes salted butter is assuming a quantity it cannot know. That matters most where the total salt is small relative to the butter — buttercream, shortbread, some biscuits — and hardly at all in a bread dough, where the salt in the butter is a rounding error beside the salt in the formula. The old argument that salted butter is older stock is not something BakeHQ can support or refute; nothing verifiable was found either way.
Where they differ
| Dimension | First | Second |
|---|---|---|
| Salt content | Varies by brand, and is not usually stated in a way that helps. | None, so the recipe controls the total. |
| Effect in buttercream or shortbread | Noticeable, because butter is most of the formula. | Predictable. |
Differences that do not matter
These are real distinctions that are unlikely to change your decision. They are listed so you can stop thinking about them rather than left out so the comparison looks decisive.
- Effect in a bread dough. Negligible — the dough’s own salt dominates. Negligible.
- Behaviour in the bake. Identical fat, identical function. Identical.
