Why it works: Cream and sugar are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 43,450 recipes. Both carry 2,3-butanedione, which smells butter, sweet. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Yolks thicken the filling and whites whip into the meringue topping.
- Sweetened condensed milk
- Provides sweetness and a thick, creamy body to the filling.
- Key lime juice
- Supplies the sharp acidity that gives the filling its characteristic tang.
- Cream of tartar
- Stabilizes the egg whites so the meringue whips up firmer and holds its shape.
- Sugar
- Sweetens the meringue and helps stabilize the whipped egg white foam.
The step that matters
Spreading the meringue over the filling. The meringue must touch the crust all around the edge so it seals and does not shrink or weep during baking. Whites beaten to stiff peaks hold their structure better when the sugar is added gradually, which helps prevent a slumped or weepy topping.
Swap the lime
How well each one fits the dish's main ingredients (egg, condensed milk, cream, sugar):
- Vanillafits better
- Coconutfits better
- Strawberryfits better
- Limethe original
Fit is the average pairing score against egg, condensed milk, cream, sugar. Candidates are from the same food group and used in at least 100 recipes.
