Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Unflavored gelatin
Sets the whipped filling so it holds its shape when sliced.
Evaporated skim milk
Whips into a light, airy base that gives the filling its body.
Lime juice
Provides the tart, acidic flavor that defines the pie.
Sweetener (in the method)
Balances the tartness of the lime juice with sweetness.

The step that matters

Slowly blend gelatin mixture into whipped milk. Gelatin that is too cold or too firm will form lumps and streaks instead of blending evenly. Adding it slowly to the whipped milk, while the gelatin is still liquid and only slightly thickened, keeps the filling smooth and airy.

Flavor stand-ins for the vanilla

  3. Vanillathe original
  4. Lemonabout as good a flavor fit

Fit is the average pairing score against gelatin, lime, sugar substitute, milk. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
