Building on a classic whiskey sour recipe, the old thyme sour adds a number of new twists to create a delightful, very fun cocktail. The cocktail was created by Michael Grissinger and is innovative on many levels. It all begins with a mix of fresh thyme and Chartreuse, which is eventually lit on fire to give the drink a sweet and herbal smoky background.
Building on that, this sour combines Irish whiskey with elderflower and homemade cinnamon-thyme syrup. Of course, in true sour fashion, there's a healthy dose of fresh lemon and a touch of egg white for that amazing texture that no other ingredient can give drinks.
- For the Cinnamon-Thyme Syrup:
- 1 cup water
- 1 1/2 cups sugar
- 2 sprigs of thyme
- 1 cinnamon stick
- For the Cocktail:

Note: while there are multiple steps to this recipe, this cocktail is broken down into workable categories to help you better plan for preparation and assembly.
Make the Cinnamon-Thyme Simple Syrup
Gather the ingredients.
In a saucepan, bring the water to a boil and stir in the sugar to dissolve.
Reduce the heat and simmer, stirring occasionally. Add the cinnamon stick and thyme and simmer for about 20 to 30 minutes, to taste.
Strain, cool, and bottle in a well-sealed container.
Make the Old Thyme Sour Cocktail
Place the two sprigs of thyme and Chartreuse in an old-fashioned glass and stir to coat the thyme.
In a cocktail shaker, add two sprigs of thyme, the whiskey, elderflower liqueur, lemon juice, cinnamon-thyme syrup, bitters, and egg white.
Dry shake to incorporate the ingredients, then add ice and shake thoroughly.
Light the liqueur-soaked thyme on fire in the glass.
Double strain the contents of the shaker into the glass to extinguish the flame.
Add lemon zest and fill with fresh ice.
Garnish with lemon and leftover thyme. Serve and enjoy.
Raw Egg Warning
Consuming raw and lightly-cooked eggs poses a risk for food-borne illness.
- The flavored syrup makes just over 1 cup, so you'll have plenty for many cocktails. It can also be used in other mixed drinks and makes an interesting sweetener for tea.
- Store the homemade syrup in the refrigerator for up to 2 weeks.
- Green Chartreuse is higher proof (55 percent ABV) than Yellow Chartreuse (40 percent ABV), so it will burn better.
- Skip the egg white if you prefer.
