- 7
Place eggs in warm water for about 15 minutes, then separate carefully, ensuring no yolk contaminates whites.

Whisk egg yolks until smooth, then add lime juice, lime zest, sweetened condensed milk, and green food coloring; whisk until blended.
- 9
In a separate bowl, beat egg whites until frothy, then add cream of tartar.
- 10

Tips
Warm eggs in water before separating to ensure whites whip to maximum volume and create a stable, tall meringue that lightens the filling significantly.
Prevent overbeating whipped cream by stopping as soon as it thickens; overbeating turns it to butter, ruining the topping's silky texture.
Chill the mixing bowl and beaters before whipping cream to achieve faster thickening and better volume.
Good to Know
Cover and refrigerate for up to 2 days. Pie continues to set slightly overnight and flavors meld. Whipped cream topping is best applied just before serving.
Prepare pie through baking and cooling up to 1 day ahead. Refrigerate covered. Whip cream topping within 2 hours of serving for best texture. Crust can be prepared and frozen up to 3 days in advance.
Serve chilled, cut into wedges. A dollop of freshly whipped cream and twisted lime slice garnish elevate presentation. Pairs well with hot coffee or chilled white wine. Ideal for dinner parties, special occasions, and warm-weather gatherings.
Common Mistakes
Do not skip the egg white separation step of warming eggs to ensure proper volume and stability of meringue.
Do not overbeat whipped cream to avoid churning it into butter.
Do not underbake the pie; 25-30 minutes ensures the filling sets without remaining custard-like.
Do not skip crust chilling; this prevents shrinkage and sticking during baking.

FAQ
Can I make this pie without eggs?
The eggs are essential for structure and texture: yolks create the custard body, whites form the airy meringue. Replacing them requires a completely different recipe and approach.
What if I don't have fresh limes?
Bottled fresh lime juice works well in a 1:1 substitution. Avoid cordial or concentrate, which contain added sugar and flavoring. Zest from bottled limes won't work; use a small amount of dried lime peel or omit zest.
How long can I keep this pie?
Refrigerate covered for up to 2 days. Do not freeze the unbaked or baked pie due to meringue sensitivity to freezing. The whipped cream topping is best added within hours of serving.
