The first recipe, Emma's, will taste more "lemony" because it uses a greater amount of lemon juice compared to Clair's recipe. Emma's recipe calls for the juice of 5 lemons, while Clair's recipe only uses the juice of 2 lemons.
When comparing the two recipes, Emma's has a higher ratio of lemon juice to water (5 lemons to 2 cups of water) compared to Clair's (2 lemons to 1 cup of water).
To quantify this, we can look at the ratio of lemons to water in each recipe:
- Emma's recipe: 5 lemons / 2 cups of water = 2.5 lemons per cup of water
- Clair's recipe: 2 lemons / 1 cup of water = 2 lemons per cup of water
Since Emma's recipe has a higher ratio of lemons to water, it will result in a stronger, more pronounced lemon flavor, making it taste more "lemony" than Clair's recipe.
