Blue Curaçao is an orange liqueur of the curaçao style, tinted vivid blue with food coloring that does not change its flavor.
Balance it as you would a clear triple sec. A small pour gives plenty of color, so the blue shows long before the orange does. Over yellow juices like pineapple it turns turquoise rather than blue, as in a Blue Hawaii.
Another blue curaçao
Will do in the same amount, though sugar runs from about 250 to 330 g per liter.
Triple Sec / Dry Curaçao
Orange liqueurs of the same family, left uncolored. A drop of blue food coloring restores the color.
Butterfly pea flower tea
Brewed strong, it turns a drink blue, but acid turns it purple, then pink, so it will not stay blue with citrus.
Blue Raspberry liqueur
Same blue, berry flavor instead of orange: the drink stays blue and loses its citrus edge.
