Prepare a martini glass by frosting the rim with a mixture of 4 parts granulated sugar and one part ginger powder.
Place the piece of ginger, the Cointreau, and the elderflower cordial in the bottom of a bar glass and muddle (mash) well together.
Assemble all the remaining ingredients and shake well with ice.
Strain into the prepared glass and place the lemon spiral on the edge of the glass.
A lemon peel will suffice if the tool is not available to prepare lemon spirals.
Created this for Oprah Winfrey at her 50th birthday celebration.
