Recipe for sea salt butter

Amount: 250 g


250 gr butter
3-5% Fleur de Sel, sea salt flakes, s. Notes


  • At first check the salt content of the butter. It’s normally 1-2% per 100 g butter. This amount has to be deducted to get the right amount of salt that has to be added to the butter.
    Let’s say 100 g butter has e.g. around 2,5 g salt. That’s 6,25 g salt in 250 g butter.
    French salted butter has 3-5% salt.
    250 g butter with 3% salt content needs 7,5 g salt in total. Therefore 1,25 g salt has to be added.
    250 g butter with 5% salt content needs 12,5 g salt in total. Therefore 6,25 g salt has to be added.
  • Remove the butter from the fridge minimum one hour before you start.
  • If the butter is soft and at room temperature then cut it in small pieces. Put it in a small plastic container with a lid. This container is later used to store the butter.
  • You can also heat the butter on low temperature on the stove. Don’t let it get liquid.
  • Add the sea salt flakes. Incorporate them in the butter with a fork.
  • Cool the sea salt butter in the fridge without delay. Use an airtight container with a lid.
  • Enjoy cold with a fresh piece of bread.


Salt content in total should be max. 5% of the butter. Check out how much salt you like best. Start with 3% and increase the amount of salt according to your taste.
