This delicate syrup is delicious with vodka in our Spiked Elderflower Lemonade but would also pair well with gin. Recipe courtesy of Erin French, chef and owner of Lost Kitchen in Freedom, ME.
Bring sugar and 2 cups water to a boil, stirring, until sugar is dissolved, about 3 minutes. Remove from heat; let cool completely.
Meanwhile, in a bowl, combine lemon juice, zest, and elderflowers. Pour syrup over flower mixture; stir to combine. Cover and refrigerate 1 day. Strain cordial through a fine-mesh sieve; discard flowers. Cordial can be refrigerated in an airtight container up to 1 month.
