Lemon ice cream is a delightful frozen dessert that combines the creamy richness of classic ice cream with the zesty brightness of fresh lemons. Perfect for summer or as a palate-cleansing finish to any meal, this homemade lemon ice cream strikes a beautiful balance between sweet and tart. Making it from scratch is easier than you might think, and the result is a treat that’s far more vibrant and flavorful than store-bought versions.
Ingredients
- 1 1/2 cups heavy cream
- 1 1/2 cups whole milk
- 3/4 cup granulated sugar
- 1 tablespoon finely grated lemon zest (from 2-3 lemons)
- 2/3 cup freshly squeezed lemon juice (from about 3-4 lemons)
- 5 large egg yolks
- 1 teaspoon pure vanilla extract
- Pinch of salt
Instructions
- Prepare the lemons: Using a microplane or fine grater, zest 2-3 lemons to get about 1 tablespoon of zest. Juice the lemons to yield about 2/3 cup of lemon juice. Set both aside.
- Infuse the cream: In a medium saucepan, combine the heavy cream, whole milk, half of the sugar (about 3/8 cup), and the lemon zest. Place over medium heat and warm until steaming but not boiling, stirring occasionally. Once it’s steaming, remove from heat, cover, and let the zest infuse for 20 minutes.
- Prepare the egg yolks: In a medium bowl, whisk together the egg yolks, remaining sugar, and a pinch of salt until the mixture is pale and slightly thickened.
- Temper the eggs: Slowly pour about 1/2 cup of the warm cream mixture into the egg yolks, whisking constantly to prevent curdling. Gradually whisk in another 1/2 cup. Then, pour the egg mixture back into the saucepan with the rest of the cream.
- Cook the custard: Set the saucepan over low-medium heat. Stir constantly with a wooden spoon or heatproof spatula, scraping the bottom and sides, until the custard thickens and coats the back of the spoon (about 170–175°F, or 77–80°C). Do not let it boil.
- Strain and chill: Remove the saucepan from heat. Strain the custard through a fine-mesh sieve into a clean bowl to remove the zest and any coagulated egg. Stir in the vanilla extract. Allow to cool for about 15 minutes, then cover and refrigerate until thoroughly chilled (at least 4 hours, preferably overnight).
- Add the lemon juice: Once the custard base is completely cold, stir in the freshly squeezed lemon juice. (Adding the juice before chilling can cause the dairy to curdle.)
- Churn the ice cream: Pour the mixture into your ice cream maker and churn according to the manufacturer’s instructions. This usually takes 20–25 minutes, until the ice cream is thick and creamy.
- Freeze: Transfer the churned ice cream to a lidded container. Press a piece of parchment or plastic wrap directly onto the surface to prevent ice crystals, then seal the container. Freeze for at least 4 hours to firm up before scooping.
- Serve: Let the ice cream sit at room temperature for 5–10 minutes before scooping for best texture. Enjoy!
Tips
- Substitutions: You can use Meyer lemons for a sweeter, floral flavor. If you’re out of whole milk, substitute with more heavy cream for a richer texture, or with half-and-half for a lighter result.
- Making without an ice cream maker: After mixing in the lemon juice, pour the base into a shallow dish. Freeze for 45 minutes, then stir vigorously with a fork. Repeat every 30 minutes for 3–4 hours until creamy and scoopable.
- Prevent curdling: Always add the lemon juice to the fully chilled custard base, not while it’s hot. Lemon juice can curdle hot dairy mixtures.
- Flavor boost: For extra lemon punch, add a few drops of lemon extract or swirl in a homemade lemon curd during the final minutes of churning.
Serving Suggestions
- Scoop lemon ice cream into bowls or cones and garnish with fresh berries, such as raspberries or blueberries, for a colorful contrast.
- Serve alongside shortbread cookies or biscotti for a classic European-style dessert.
- Pair with a slice of pound cake, angel food cake, or lemon tart for a double-lemon treat.
- Top with a drizzle of berry coulis, honey, or a sprinkle of toasted coconut for added flavor and texture.
- Use as a palate cleanser between courses at a special dinner.
Variations
- Lemon-Basil Ice Cream: Add a handful of fresh basil leaves to the cream while infusing with lemon zest. Strain out the basil with the zest for a subtle herbal note.
- Lemon Poppy Seed: Stir in 1 tablespoon of poppy seeds just before churning for a crunchy texture reminiscent of lemon poppy seed muffins.
- Vegan Lemon Ice Cream: Substitute the cream and milk with full-fat coconut milk, and use 3/4 cup of maple syrup or agave instead of sugar. Omit the eggs, and thicken with 2 tablespoons of cornstarch.
- Lemon-Lime: Replace half the lemon juice and zest with lime for a citrusy twist.
- Lemon Swirl: After churning, ripple in homemade or store-bought lemon curd for pockets of intense flavor.
Storage and Reheating
Store lemon ice cream in an airtight container in the coldest part of your freezer. For best quality, enjoy within 2 weeks. Homemade ice cream is best within the first week, as it can become icy over time. To scoop easily, let the container sit at room temperature for 5–10 minutes to soften slightly; do not microwave, as it can melt unevenly. Never refreeze ice cream that has melted completely, as this can affect texture and food safety.
Frequently Asked Questions
- Can I use bottled lemon juice instead of fresh?
- Fresh lemon juice is highly recommended for the best flavor. Bottled juice often contains preservatives and lacks the bright, aromatic quality of fresh-squeezed lemons. If you must use bottled, look for one with no additives and use fresh zest to boost flavor.
- How do I prevent my ice cream from becoming icy?
- Homemade ice cream can become icy if too much water is present or if it’s not churned properly. Using enough fat (cream and egg yolks) helps prevent ice crystals. Make sure the base is thoroughly chilled before churning, and store the finished ice cream with a layer of plastic wrap or parchment pressed against the surface to minimize air exposure.
- Is it safe to eat ice cream made with raw eggs?
- This recipe cooks the egg yolks to 170–175°F, which is considered safe and pasteurizes them. Avoid using uncooked eggs in ice cream unless they are pasteurized, as raw eggs can pose a risk of foodborne illness.
- What if I don’t have an ice cream maker?
- You can still make lemon ice cream using the freezer method described above. The texture will be less creamy and more like a semifreddo or frozen custard, but it will still be delicious.
- Can I make this recipe dairy-free?
- Yes, substitute the cream and milk with full-fat coconut milk or a blend of coconut milk and almond milk. Use a vegan thickener like cornstarch instead of egg yolks, and sweeten with your preferred plant-based sweetener.
- Why did my ice cream base curdle?
- Adding lemon juice to a warm or hot dairy mixture can cause curdling due to the acid in the juice. Always chill the custard base thoroughly before stirring in the lemon juice. If curdling does occur, you can try straining the mixture, but the texture may not be as smooth.
