Bourbon Sour with Egg White

Bourbon Sour with egg white: texture before flavour

Egg white is the most effective upgrade you can make to a whiskey sour. The flavour stays familiar; what changes is mouthfeel, aroma delivery and the look of the drink. A good one has a dense, glossy cap that holds bitters without sinking.

Why the dry shake matters

The dry shake, without ice, denatures the proteins in the white and traps air, which builds the foam. The second shake with ice chills the drink and adds the dilution the recipe needs. For the tightest foam, reverse the order: shake with ice first, strain the drink off the ice, then dry shake the chilled liquid for 10 seconds.

Exact measures

A small egg white measures about 30 ml, so half of one suits a single drink; much more than 25 ml gives you a meringue that smells eggy. Use fresh eggs, keep the shells clean and serve straight after shaking.

How strong is a Bourbon Sour?

At 2:0.75:0.5 with a 45% bourbon, the drink lands near 16% ABV once shaken and diluted, with roughly 24 ml of pure alcohol and about 200 kcal per serve.

Substitutions and fixes

• No egg: 20-25 ml of aquafaba from a can of chickpeas foams almost as well; a few drops of saline tighten it.
• Foam collapses in a minute: fat is the culprit, whether a trace of yolk, an oily shaker or citrus peel left in the tin.
• Tastes eggy: the white is stale or there is too much of it. Grate the bitters over the foam, which masks the sulphur.

Bourbon Sour FAQ

Can I make a Bourbon Sour without egg?

Yes. Aquafaba at 20-25 ml per drink is the closest match, and pasteurised egg white behaves exactly like fresh. Neither changes the flavour.

Why does my foam disappear so fast?

Almost always fat or under-shaking. Any trace of yolk or oil breaks the protein network that holds the bubbles.

Can I batch Bourbon Sours for a party?

Batch the bourbon, lemon and syrup a day ahead and refrigerate. Add the egg white and shake each drink to order, because a pre-shaken sour loses its foam fast.
