I made this with lemon peel instead of orange and vodka instead of brandy as I thought it would complement the flavors of the Honey & Hearth cocktail best, but feel free to try the original if you prefer; I think either would be delicious. Give yourself a few days to make this; most of the time is inactive. Adapted lightly from Serious Eats.
Store the liqueur in a cool, dry place for up to 1 year. If the mixture becomes cloudy or develops an off-flavor, discard.
