The Rusty Nail is a classic made with Scotch and Drambuie, but here it’s transformed into a Sour: lemon juice and egg white turn it into a creamy, balanced drink. The smoky depth of the whisky remains, while the acidity and sweetness bring balance. A drink that leaves you wanting more – perfect for whisky lovers seeking variety.
And this is what you need for the Rusty Nail Sour with egg white
5 cl Scotch Whisky (smoky, e.g. Islay)
2 cl Drambuie (or homemade honey-cinnamon syrup with a Scotch base)
2 cl freshly squeezed lemon juice
1 cl sugar syrup (1:1)
1 egg white (fresh, room temperature)
1 splash of Angostura bitters (for garnishing)
Key points
Shake the egg white *before* adding ice – that’s the trick to a stable, silky texture. Many bartenders skip this step, but it’s the only way to avoid lumps. Use a smoky Scotch (e.g. Laphroaig or Ardbeg) to stand up to the spices in Drambuie. If you don’t like Drambuie: replace it with 1.5 cl honey syrup + 0.5 cl Scotch + a pinch of cinnamon – this gives a similar spice profile but with less alcohol.
Variations
- Smoky Rusty Nail Sour — Replace the Scotch with a heavily peated whisky (e.g. 4 cl Ardbeg + 1 cl Drambuie) and reduce the sugar syrup to 0.5 cl. Garnish with smoked salt on the rim.
- Rusty Nail Fizz — After straining, top with 3 cl chilled soda water. The egg white remains, but the drink becomes lighter and more effervescent.
Frequently Asked Questions
Can I use pasteurised egg white?
Yes, but fresh egg white gives a better texture. Pasteurised versions are safer but less stable when foaming. If you’re concerned: replace it with 2 cl aquafaba (chickpea water) – the result is similarly creamy.
Why does my Rusty Nail Sour taste bitter?
Too much Drambuie or not enough acidity. Drambuie is intense – stick to 2 cl and adjust the lemon juice (up to 2.5 cl). A dash of sugar syrup can help if the whisky is too harsh.
Can I make this drink without egg white?
Yes, but it will be flatter and less creamy. If you don’t like egg white, shake the drink for longer with ice (20 seconds) and double-strain – this adds a bit more volume.
