There’s something wonderfully simple about a Lemon Squash. It’s bright, bubbly, and just sweet enough to feel like a treat without going overboard. This has been my go-to drink on warm afternoons or when I want something refreshing without alcohol. It’s like a sparkling lemonade-but with a little more charm.

Lemon Squash
What You’ll Need
Prep time: 5 minutes
Servings: 1
Equipment: Highball glass or mason jar, spoon for stirring
Ingredients
– 1 oz (30 ml) freshly squeezed lemon juice (about half a lemon)
– 0.5 oz (15 ml) simple syrup (or to taste)
– Soda water, to top up (about 4-6 oz / 120-180 ml)
– Ice cubes, enough to fill the glass
– Optional garnish: lemon slice, fresh mint sprig
Method
- Fill a highball glass (or mason jar) with ice.
- Pour in the lemon juice and simple syrup.
- Give it a good stir to combine-this helps the syrup mix evenly with the juice.
- Top up with soda water until the glass is full. Stir gently one more time so you don’t lose those lovely bubbles.
- Add a slice of lemon or a sprig of mint for a fresh, pretty finish.
Tips for the Best Lemon Squash
– Use fresh lemon juice. It really makes a difference. Bottled juice can taste flat or overly sour.
– Adjust the sweetness to your liking. Start with less syrup-you can always add more.
– Stir gently after adding soda so you don’t lose the fizz.
– Simple syrup is just equal parts sugar and water heated until the sugar dissolves. You can make a batch and keep it in the fridge for up to 2 weeks.
Make-Ahead Notes
You can mix the lemon juice and syrup up to a day in advance-just keep it chilled in the fridge. Add the soda water right before serving to keep it sparkling.
Ingredient Swaps
– Syrup: Use honey or agave nectar instead of simple syrup for a natural sweetness. Just stir a bit longer to help it dissolve.
– Soda water: Swap with tonic water for a more bitter edge or ginger ale for a warm, spicy twist.
– Garnish: Try basil, rosemary, or even a thin slice of cucumber for something different.
Common Mistakes to Avoid
– Don’t skip the stir-if the syrup sits at the bottom, your first sip will be all lemon and your last sip will be way too sweet.
– Avoid using flat soda water; it takes away the refreshing sparkle.
– Be careful not to over-sweeten. You want to taste the lemon!
What It Tastes Like
A good Lemon Squash hits the perfect balance-bright lemony tartness with just enough sweetness to round it out. The bubbles make it feel light and playful. It’s like sunshine in a glass.
I’ve made this drink countless times, and here’s a little tip I learned: if you want to take it up a notch, rub a bit of lemon zest on the rim of the glass before you pour. It gives every sip an extra citrusy punch.
Serving Suggestions
Serve it cold, over lots of ice. It’s great on its own or with:
– Grilled chicken: The acidity cuts through the richness beautifully.
– Fresh salads: Especially ones with feta or citrus-based dressings.
– Fish and chips: A classic combo-zesty drink, crispy fish, salty fries.
Fun Variations
Raspberry Lemon Squash
– Add a handful of fresh raspberries.
– Muddle them with the lemon juice and syrup before adding soda water.
Minty Lemon Squash
– Add 5-6 fresh mint leaves.
– Muddle with the lemon juice and syrup to release the oils, then top with soda.
Spicy Ginger Lemon Squash
– Use ginger ale instead of soda water.
– Muddle a thin slice of fresh ginger with the lemon juice and syrup for a warming kick.
Party Pitcher Version
Want to make it for a crowd? Multiply the lemon juice and syrup by however many servings you want, and mix them in a large pitcher. Keep it chilled. When it’s time to serve, pour over ice and top each glass with soda water so it stays fizzy.
FAQ
Can I make it boozy?
Absolutely. Add a shot (1 oz / 30 ml) of vodka, gin, or white rum for a refreshing grown-up version.
Is it kid-friendly?
Yes! The non-alcoholic version is basically a fancy lemonade.
Too sweet?
Start with less syrup. You can always add more, but you can’t take it out.
Can I make it ahead of time?
Mix the lemon juice and syrup in advance, but wait to add the soda water until just before serving.
Winter version?
Try it warm! Use hot water instead of soda, and add a cinnamon stick or a clove-infused syrup for a cozy twist.
This drink is one of those simple pleasures that never gets old. Whether you keep it classic or try a new variation, Lemon Squash is always a refreshing pick-me-up that’s easy to love and even easier to make.
