OK here it is
Original recipe as printed in The South American Gentleman's Companion, 1951 by Charles H. Baker Jr:
Specs I used, as printed in the Bartender's Choice App
Spanish Monk Cocktail
1.5 oz Gin
0.5 oz Green Chartreuse
3/4 oz Lemon
1/2 oz Simple
Egg White
No Garnish
The result is such a beautiful, smooth, tart, herbal cocktail where everything works together in perfect harmony. The egg white is a must, giving it a smooth creamy texture that just 'holds' everything together. Modern version says no garnish (probably because the 50's recipe calls for one of those freakish green cherries), but a quality maraschino cherry would be welcome here.
