Luis Buñuel’s martini recipe:

“For those who are still with me, let me give you my personal recipe, the fruit of long experimentation and guaranteed to produce perfect results. The day before your guests arrive, put all the ingredients – glasses, gin, and shaker – in the refrigerator. Use a thermometer to make sure the ice is about twenty degrees below zero (centigrade). Don’t take anything out until your friends arrive; then pour a few drops of Noilly Prat and half a demitasse spoon of Angostura bitters over the ice. Shake it, then pour it out, leaving only the ice, which retains a faint taste of both. Then pour straight gin over the ice, shake it again, and serve.”
– My Last Sign (1983)
