According to reports Ernest Hemingway created a cocktail to ease nausea and stomach upset. If it worked for Hemingway, it'll work for me. This is the American absinthe version of his 'Death in the Afternoon' from Wondrich.
1.5 oz Absinthe
4 oz Brut champagne
Add absinthe to a champagne flute. Pour champagne over. Serve well-chilled.
