Amer Picon is a French bitter-orange aperitif liqueur flavored with dried orange peel, gentian root and cinchona bark.
Ramazzotti
The most common stand-in. Use the same amount, plus a dash of orange bitters per 15 ml.
Amaro CioCiaro
Used the exact same way, with the dash of orange bitters.
Bigallet China-China
Also works measure for measure. At 40%, it makes the cocktail stronger.
Torani Amer
Swaps straight in as well. It tastes more vegetal, so add orange bitters to taste.
A last resort. It makes a sweeter cocktail with no bitter edge.
Today's Picon is much lower in strength than the 19th-century original and has been reformulated over the years. Older recipes that call for it were written for a different bottle.
