Toasted hazelnuts deliver an incomparable flavor to this shortbread. For optimum flavor, toast hazelnuts in a medium temperature oven until the heart of hazelnuts are golden brown. I do not advise to grind hazelnuts in a food processor without another ingredient present; it most often leads to hazelnut paste. Adding pastry flour to the toasted hazelnuts prevents this from happening.

For optimum flavor prepare dough at least one day in advance as in most cases a fuller aroma develops.

Needed for Assembly:

Toasted hazelnut shortbread dough, recipe below
Lime Curd, recipe from On Baking pg 493.


  1. Place a small amount of candied kumquats onto pre-baked hazelnut shortbread.
  2. Pipe chilled lime curd onto kumquat and top with another shortbread.

  5. Roll the dough on a lightly floured surface about 3 credit cards thick and cut into desired shapes. If desired sprinkle with chopped hazelnuts.

    In this recipe could hazelnut be substituted with almonds or is that hazelnut brings all of the flavors together better than almond?

    Chef, does the candied kumquat still has the bitter-sour taste from the skin or was it candied without the skin on?

    This looks amazing, not a fan of kumquats but will give this a try. Can the candied fruit be substituted by others that wont overpower the hazelnut shortbread, flavor wise?

    I just bought some kumquat to make some tea at home, but now I’ll have an alternative use for them. It’s also a relief to see in that “kumquats are some of the quickest and least complicated fruits to candy.”
