Great flavours but a touch sweet for me. I tried adding 6 drops of cardamom bitters and found that made it more balanced and brought out the herbal flavours in the Chartreuse a bit more
I love mojitos and elderflower but unfortunately this is vile. The mint would probably be better muddled in the lime juice and liqueur to avoid bringing out so much bitterness, and crushed ice with multiple churns just makes it watery and bland.
