Choosing the Best Limes
Fresh limes make the biggest difference.
Look for:
- Bright green color

Key limes are traditional, but regular limes work perfectly too.
Making the Perfect Crust
Step 1: Crush the Biscuits
Crush biscuits into fine crumbs using a food processor or rolling pin.
Step 2: Mix With Butter
Combine crumbs with melted butter and sugar until texture resembles wet sand.
Step 3: Press Into Pie Pan
Press mixture firmly into bottom and sides of pie dish.
Step 4: Bake Briefly
Bake at 175°C (350°F) for 8–10 minutes, then cool.
This keeps the crust firm and crunchy.
Preparing the Creamy Filling
Step 1: Whisk Egg Yolks
Whisk yolks until slightly thickened and smooth.
Step 2: Add Condensed Milk
Pour in condensed milk and mix until creamy.
Step 3: Add Lime Juice and Zest
Slowly mix in lime juice and zest. The mixture will naturally thicken.
Baking the Pie
- Pour filling into cooled crust.
- Bake at 175°C (350°F) for 12–15 minutes.
The center should be set but slightly soft.
Cooling and Chilling
Cooling is important for texture:
- Let pie cool to room temperature.
- Refrigerate at least 3–4 hours.

The filling becomes firm, smooth, and sliceable.
