Can you use regular limes in a key lime pie?

Yep! Key limes can be tricky to find in regular supermarkets if you don’t live in Florida, California, Texas in the states, or in Mexico, Central America, and South America. Regular limes will work just fine. I found that about 4 to 5 limes make about ¾ cup lime juice. If you can find key limes, it will take around 20 limes because they are much smaller.

Tip: Skip the prepackaged lime or key lime juice. Although tempting, bottled lime juice contains chemicals and additives that make it taste “off.” 

Should I use Greek yogurt or sour cream?

I opted for Greek yogurt for this key lime pie because it has no saturated fat and fewer calories than sour cream. I also like how greek yogurt comes in single one-cup servings so there is no fuss trying to get the correct amount into a measuring cup. Both sour cream and greek yogurt add creaminess to the pie.

Recipes that call for eggs 

Some variations call for the use of 4 to 5 egg yolks instead of sour cream/Greek yogurt. Personally, I didn’t like the pie with eggs yolks. It made it more of a gelatinous custard. There are people out there that do prefer this, so if this is you, just swap out the yogurt for 4-5 egg yolks.

    Can you use “Regular Milk” instead of Sweetened Condense Milk?

  • I would not substitute regular milk. The sweetened condensed milk is what sweetens the yogurt and mellows the lime. It is also much thicker than regular milk so the consistency will be off as well. Hope that helps!

  • I think this would be a-ok, but definetly make sure you like the taste of the flavored yogurt first. I would also add in the lime juice to taste to make sure it isn’t overpowering!
