Why it works: Lemon and lime match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 1,289 recipes. Both carry beta-phellandrene, which smells minty, terpene. The science ↓
Lemon-Lime Soda I
Serves 4Ingredients
Directions
Make the syrup
Remove the zest from the lemons and limes in strips, leaving behind the bitter white pith.
Combine the sugar and zest in a container, and let this sit in the fridge for 24 hours. The sugar will extract the liquid from the citrus peels and produce a syrupy liquid.
Strain the solids out of the peel and sugar mixture.
Mix the peel and sugar mixture with lime juice. This should produce slightly under ½ cup (120 ml) of syrup.
Make the soda
To make the finished soda, mix 1 volume of syrup with 5 volumes of carbonated water.
Nutrition, whole recipe (rough)
Counts 3 of 4 ingredients. The other 1 aren't in our nutrition table and add nothing above, so the real totals are higher.
What these numbers assume: 3 portions
| Ingredient | Portion assumed | kcal |

| Sugar | 1 tbsp (12.5g) granulated | 49 |
| Lemon | juice of 1 lemon (48ml) | 12 |
| Lime | juice of 1 lime (44ml) | 11 |
| Water | not in our table | 0 |

The flavor team
The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Lemon and sugar barely smell alike, yet cooks put them together in 53,532 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- White sugar
- Draws liquid out of the citrus peels and sweetens the syrup.
- Lemon zest
- Supplies aromatic oils and flavour to the syrup.
- Lime zest
- Supplies aromatic oils and flavour to the syrup.
- Lime juice
- Adds acidity and bright citrus flavour to the syrup.
The step that matters
Removing the zest without pith. The white pith under the peel is bitter. Cutting only the coloured outer layer in strips keeps that bitterness out of the syrup and the finished soda.
Swap the lime
How well each one fits the dish's main ingredients (lemon, sugar):
- Orangefits better
- Limethe original
- Vanillafits about as well
- Blueberryfits less well
Fit is the average pairing score against lemon, sugar. Candidates are from the same food group and used in at least 100 recipes.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
