- Use only the
best butter - I highly recommend Elle&Vire, one of my favourite French butters that can be found in baking shops and major supermarkets.
- If you want to make the batter in a stand mixer, combine the softened butter, sifted icing sugar, fleur de sel, vanilla and egg white in the mixing bowl. Use a paddle attachment and mix on medium speed until combined. Sift in the flour and mix on low speed until just combined then mix in the milk/water. Use a spatula to finish mixing by hand.
- No fleur de sel? Replace with 1 pinch of fine sea/table salt.
