Method
- Cream. Cream the softened butter and sugar together until pale, light and airy.
- Add the egg. Beat in the egg (and the vanilla extract, if using) until fully combined.
- Add the dry ingredients. Sift the vanilla sugar, potato starch and all-purpose flour together, then sift into the butter mixture.
- Bring it together. Knead gently until you have a firm, smooth dough. Chill 30 minutes if it feels too soft to roll.
- Roll. Heat the oven to 350°F (180°C). Roll the dough into small balls, about 20 g each, and place them on parchment-lined baking sheets — no more than about 20 per tray so they don't spread into each other.
- Press the pattern. Press each cookie down gently with a fork to make the classic ridged pattern. If the fork sticks, dip it in a little potato starch between cookies.
- Bake. Bake for 12–14 minutes, starting to check at 11. Sandnøtter should stay pale — do not let them brown.
- Cool on the tray. Leave them on the tray until completely cool. They're fragile straight from the oven and firm up as they cool.
Notes
Chef's tip — the starch is the whole point. The high ratio of potato starch is what gives sandnøtter their sandy, melt-in-the-mouth crumb — that's the "sand" in the name. In the US, buy potato starch (sometimes labeled potato starch flour), not potato flour. More on why in the post below.
