Jarnac Sour Cocktail

This Jarnac sour cocktail recipe is delicious and easy to make. It is creamy, foamy and a classic.

This cocktail is a classic that hardly anyone has heard of. Including me.

I found it when I was surfing the web for inspiration. I loved the way it looked so I knew I had to make it.

I also loved that it has an egg white in it. That’s what makes it so foamy!

Now, of course it is a raw egg white. Here is an article that explains the dangers of eating them. But since the odds of my getting salmonella are slim, I took the chance.

Helpful tips

  • Make your own simple syrup as it is so easy. Here’s how: Add 1 cup of water and 1 cup of sugar to a small to medium saucepan. Heat on medium and stir as the sugar melts. Lower to a simmer and cook for 5 minutes. Let cool totally before adding to a cocktail.
  • You will need to separate the yolk from the whites. Here’s an easy way that my grandmother used to do. Crack an egg and put it in one of your hands. With your hand over a measuring glass, let the egg white run through your slightly separated fingers and into the glass. You can transfer the yolk between both of your hands until all the white has dropped into the glass. Either toss the yolk or save it and use it in an omelette. 🙂

How to make a jarnac sour cocktail

Pre-step

Get a cocktail shaker and DO NOT fill it with ice. This cocktail is a dry shake which means no ice at the beginning. The reason is because it will the egg white foam up and thicken.

Also get a measuring glass and coupe glass.

After measuring out the ingredients, add to the shaker.

Step one

Gather the ingredients – cognac, dry vermouth, simple syrup, lemon and egg.
