I was out of triple sec so I used grand Marnier. Also I live in the US so I subbed China China for Picon. Is it still the same drink? Who knows. But it was surprisingly good.
Also works very well with Lillet rouge...maybe slightly drier but only marginally. Also tried it with orange bitters, aiming to pick up the distinct orange flavours from the non-wine ingredients. A nice enough drink resulted but with a rather less subtle, sweeter orange hit up front. What a brilliant original recipe!
