Recipe Questions
Can I make key lime pie without eggs?
Yes. The acidity of lime juice thickens the condensed milk, so eggs are not required.
How long does key lime pie need to chill?
At least 6 hours, but overnight gives the best texture.
Can I use bottled key lime juice?
Yes. Bottled key lime juice works well if fresh key limes aren’t available.
Why is my key lime pie too soft?
Use the correct ingredient ratios and chill overnight for the best texture.
