Build

30 ml Henri Bardouin Pastis
10 ml Grenadine
Cold water to top (about 150 ml)
Garnish: none

Method

Pour the pastis into a tumbler. Add the grenadine — it sinks and pools at the bottom. Top slowly with very cold water; the louche turns a warm pink-red as it blooms. Serve without ice. Stir once gently if you want to even the colour.
