A Whiskey Sour hits that sweet spot between zingy citrus and smooth, bold whiskey. It’s crisp, balanced, and refreshingly simple — the kind of cocktail that feels just right whether you’re winding down after a long day or hosting friends for a cozy evening. I’ve made this drink countless times, and it never fails to impress. Let’s break it down into something you can easily shake up at home.
Watermelon Whiskey Sour
What You’ll Need
Prep time: 5 minutes
Serves: 1
Glass: Old-fashioned or coupe
Ingredients
– 60ml (2 oz) whiskey (bourbon or rye both work great)
– 22ml (¾ oz) freshly squeezed lemon juice
– 15ml (½ oz) simple syrup (see tips below)
– Ice cubes
– Maraschino cherry and orange slice, for garnish (optional)
Equipment
– Cocktail shaker (or a jar with a lid works in a pinch)
– Jigger or measuring spoons
– Fine strainer (optional, for a smoother pour)
– Old-fashioned glass or coupe glass
Method
- Chill your glass. Pop it in the freezer or fill it with ice water while you prep. This helps keep your drink cool without over-diluting it later.
- Fill your shaker with ice. Add the whiskey, lemon juice, and simple syrup.
- Shake it up. Give it a good, strong shake — about 15 seconds — until the outside of the shaker feels cold. This chills and blends the drink while adding just the right amount of dilution.
- Strain into your glass. Discard the ice from your chilled glass and strain the drink in. If you like a cleaner finish, use a fine mesh strainer.
- Garnish. Add a cherry and a slice of orange for a classic touch. Totally optional, but it makes the drink feel extra special.
Tips & Tricks
– Use fresh lemon juice — it makes all the difference. Bottled juice tends to be too sharp and lacks the brightness of fresh.
– Make your own simple syrup: Just mix equal parts sugar and hot water until the sugar dissolves. Let it cool before using. You can store it in the fridge for up to 2 weeks.
– Prefer it less sweet? Cut the syrup to 10ml (about ⅓ oz), or use a tart lemon to balance it naturally.
– Want to mix things up? Try swapping the syrup for honey or agave nectar for a twist.
– Batching for a party? Mix the whiskey, lemon juice, and syrup in a pitcher ahead of time. Store it in the fridge and shake individual servings with ice when ready.
Make-Ahead Notes
You can prep a batch of the base (whiskey, lemon juice, syrup) and store it in the fridge for up to 2 days. Don’t add ice until serving — it’ll water it down over time. If you’re adding egg white (see below), mix fresh for each drink.
Variations to Try
Boston Sour
– Add 1 egg white to the shaker before mixing.
– Dry shake (no ice) for 10 seconds, then add ice and shake again.
– This gives the drink a velvety texture and a frothy top. I thought I’d share one of my favorite after-dinner versions — it’s silky smooth and feels like a cocktail and dessert all in one.
New York Sour
– Make a classic Whiskey Sour, then float 15ml (½ oz) of red wine on top by slowly pouring it over the back of a spoon.
– The wine adds a fruity, rich layer that looks gorgeous and tastes even better.
Winter Sour
– Infuse your whiskey with cinnamon sticks or cloves for a few hours.
– Make the cocktail as usual — the spice adds warmth that’s perfect for chilly nights.
Amaretto Sour
– Swap the whiskey for Amaretto liqueur.
– It’s nutty, sweet, and super smooth — a great option if you’re not big on whiskey but still want that sour bite.
Non-Alcoholic Version
– Mix 22ml (¾ oz) lemon juice, 15ml (½ oz) simple syrup, and 2 dashes of bitters with ice.
– Shake and strain into a glass. Garnish the same way for that classic look.
Ingredient Swaps
– No simple syrup? Use a teaspoon of sugar and stir well before shaking (though syrup blends better).
– No lemon? Fresh lime juice works in a pinch, but it will taste a bit sharper.
– Vegan? Skip the egg white or use 2 tablespoons of aquafaba (liquid from canned chickpeas) to get that same frothy finish.
Serving Suggestions
This drink shines with food. Try it with:
Barbecue
The citrus cuts through fatty, smoky meats beautifully — think ribs or pulled pork.
Seafood
Grilled shrimp or fish tacos get a lift from the lemony kick.
Cheese Boards
Aged cheddar, gouda, or even blue cheese pairs well with the whiskey’s warmth and the drink’s tart edge.
Quick Q&A
Can I make a Whiskey Sour without a shaker?
Yep! Just stir everything with ice in a mixing glass or jar, then strain into your serving glass. It won’t get as frothy, but it’ll still taste great.
What’s the best whiskey to use?
Bourbon gives a smooth, slightly sweet finish. Rye adds a bit more spice and bite. Try both and see which you prefer.
How do I get that frothy top without using egg?
Aquafaba is your friend — it gives you that same foamy layer without the eggy taste.
How strong is a Whiskey Sour?
It’s moderate — not too boozy, not too light. If you want to lighten it up, just add a splash of soda water on top.
Storage
Leftover mix (without ice or egg white) can be stored in the fridge for up to 2 days. Shake with fresh ice before serving. Once made, drink it within 30 minutes for the best flavor and texture.
