1. Gather Your Ingredients
For the frozen lemonade:
- One and a half cups fresh lemon juice (about 8 to 10 lemons)
- One cup granulated sugar
- One cup water for simple syrup
- Four cups cold water
- Four cups ice cubes
- One tablespoon lemon zest (from 2 to 3 lemons)
- Pinch of salt
For serving and variations:
- Fresh lemon slices for garnish
- Fresh mint sprigs
- Additional ice if needed
- Optional: fresh strawberries, raspberries, or watermelon for fruit variations
- Optional: vodka or white rum for adult versions
2. Make Fresh Lemon Juice
Roll each lemon firmly on the counter with the palm of your hand before cutting. This breaks down the membranes inside and makes the lemons release more juice. Cut the lemons in half crosswise. Use a citrus juicer, reamer, or even just your hand to squeeze the juice from each lemon half into a bowl. Work over a fine mesh strainer to catch seeds and large pulp pieces, though a little pulp adds character and is perfectly fine. You’ll need about 8 to 10 lemons to yield one and a half cups of juice. Fresh lemon juice is absolutely essential for this recipe—bottled lemon juice simply cannot compare in flavor or brightness. Measure out exactly one and a half cups.
3. Zest the Lemons
Before juicing your lemons, use a microplane or fine grater to remove the bright yellow zest from 2 to 3 of them. Be careful to only remove the yellow outer layer, not the white pith underneath, which is bitter. The zest contains aromatic oils that intensify the lemon flavor without adding extra acidity. You’ll need about one tablespoon of zest. Set the zest aside in a small bowl. The zest is optional but highly recommended as it adds an extra dimension of lemon flavor that makes your frozen lemonade taste more complex and authentic.
4. Make Simple Syrup
In a small saucepan, combine one cup of granulated sugar with one cup of water. Place over medium heat and stir constantly until the sugar completely dissolves, about 3 to 4 minutes. Don’t let it boil, just heat it until the liquid is clear with no sugar crystals visible. Remove from heat and stir in the lemon zest and a pinch of salt. The salt enhances the lemon flavor and balances the sweetness. Let the simple syrup cool to room temperature, about 15 to 20 minutes. You can speed this up by placing the pan in an ice bath or refrigerating it. Making simple syrup instead of adding granulated sugar directly ensures the sugar dissolves completely and creates a smoother texture.
5. Combine the Lemonade Base
In a large pitcher or bowl, combine the fresh lemon juice, cooled simple syrup (strain out the zest if you prefer, or leave it in for extra flavor), and four cups of cold water. Stir everything together thoroughly. Taste the mixture at this point and adjust as needed. If it’s too tart, add another quarter cup of simple syrup or a few tablespoons of sugar dissolved in a bit of warm water. If it’s too sweet, add more fresh lemon juice, starting with two tablespoons at a time. Remember that freezing will slightly dull the flavors, so you want the mixture to taste just a bit more intense than you’d want regular lemonade to taste.
6. Prepare for Freezing
Pour the lemonade mixture into a shallow freezer-safe container, like a 9-by-13-inch metal baking pan. Metal conducts cold better than glass or plastic, so it freezes faster and more evenly. The shallow depth is important because it creates more surface area for faster freezing and easier scraping later. Cover the pan tightly with plastic wrap or aluminum foil. Place it in the freezer on a flat surface. Set a timer for 1 hour. This first freezing period begins the process of creating that perfect slushy texture.
7. Create the Slushy Texture
After 1 hour, remove the pan from the freezer. Use a fork to scrape and stir the partially frozen mixture, breaking up any ice crystals that have formed around the edges. The edges will be more frozen than the center at this point. Return the pan to the freezer. Repeat this scraping and stirring process every 45 minutes to 1 hour for the next 3 hours. Each time you scrape, you’re breaking up ice crystals and incorporating air, which creates that fluffy, slushy texture rather than a solid block of ice. By the fourth or fifth scraping session, the entire mixture should have a uniform, fluffy, snow-cone-like consistency.
8. Blend to Perfection
Once the lemonade base is completely frozen and fluffy, you have two serving options. For the smoothest, most uniform texture, transfer the frozen lemonade mixture to a high-powered blender. Add four cups of ice cubes. Blend on high speed, using the tamper if your blender has one, until the mixture is completely smooth and slushy with no large ice chunks remaining. This should take about 1 to 2 minutes. You may need to work in batches depending on your blender size. The blending method creates the smoothest, most professional texture similar to what you’d get at a frozen lemonade stand.
9. Alternative Serving Method
If you prefer a more rustic texture or don’t want to use a blender, simply scrape the frozen lemonade granita-style directly from the pan with a fork, creating fluffy ice shavings. Pile these shavings into glasses and serve immediately. This method gives you a more crystalline, Italian granita-style texture that’s equally delicious and refreshing. It’s also easier if you’re making this for a crowd since there’s no blending involved. You can scrape portions as needed and keep the rest frozen in the pan.
10. Serve and Garnish
Pour or scoop the frozen lemonade into tall glasses, filling them about three-quarters full. The mixture should have a thick, slushy consistency that you can drink through a straw but that also holds its shape somewhat like soft-serve. Garnish each glass with a fresh lemon slice on the rim and a sprig of fresh mint tucked into the top. If the consistency seems too thin, add more ice to each glass. If it’s too thick and icy, let it sit for a few minutes at room temperature to soften slightly, or add a splash of cold water or lemon-lime soda and stir. Serve immediately with thick straws or spoons.
Tips for Perfect Results
- Use fresh lemon juice exclusively. Bottled lemon juice tastes artificial and flat compared to the bright, vibrant flavor of freshly squeezed lemons.
- Roll lemons before juicing to break down the interior membranes and release more juice. Room temperature lemons also juice more easily than cold ones.
- Make simple syrup instead of adding granulated sugar directly. This ensures complete dissolution and creates a smoother texture without any gritty sugar crystals.
- Taste and adjust the sweetness before freezing. The mixture should taste slightly more intense than you want the final product since freezing dulls flavors.
- Use a shallow, metal pan for freezing. The large surface area and metal’s conductivity create the best texture and fastest freezing time.
- Scrape the mixture regularly as it freezes. This is what creates that perfect slushy texture rather than a solid ice block that’s impossible to scoop.
- For instant frozen lemonade anytime, freeze the lemonade base in ice cube trays. When ready to serve, blend the lemonade ice cubes with a splash of water until slushy.
- Make fruit variations by adding one cup of pureed strawberries, raspberries, or watermelon to the lemonade base before freezing. Strain out seeds for the smoothest texture.
- For adult frozen lemonade, add two ounces of vodka, white rum, or tequila to each serving glass after blending. The alcohol prevents the lemonade from freezing solid if you try to make boozy versions in advance.
- Store leftover frozen lemonade in a freezer-safe container for up to 2 weeks. It will freeze solid, so let it thaw for 10 to 15 minutes at room temperature, then scrape with a fork or reblend before serving to restore the slushy texture. The texture won’t be quite as perfect as freshly made but will still be delicious and refreshing.
