Thank you for the recommendation; I'll give it a try. I was able to get hold of actual Picon Amer a few years ago, but that's no longer a viable solution.
Love this drink, but I have two questions. What would you substitute for the Amer Picon for those of us in the USA (where it's not available)? Have you tried this with Picon Biere, which was the only Picon I could find in France last summer? How does that compare to the Amer? Thanks everyone!
