What is demi-sel butter and how does it differ from salted butter?
Demi-sel butter contains 0.5–3% salt by weight, less than standard salted butter (3–4%). French demi-sel uses fleur de sel or fine sea salt, creating subtle brininess and longer shelf life.
Why is Belgian butter different from American butter?
Belgian butter typically has higher fat content (86%+) and uses coarse sea salt crystals instead of fine salt, giving a more pronounced salt bite and richer mouthfeel.
Can you use these butters interchangeably in recipes?
Yes for most cooking, but salted varieties alter seasoning balance. For baking, unsalted is preferred for precise salt control. For finishing dishes or charcuterie, the salt type and crystal size noticeably affect flavor.
How should each butter be stored?
Keep all three refrigerated in their original packaging or an airtight container for up to 3 months. Salted and demi-sel varieties last slightly longer than unsalted due to salt's preservative effect.
