So, could I use bottled juice or regular limes instead?

The only difference among the three was the pop in of juice used.

This is my favorite because it has the best lime flavor, said the one taster.

I was surprised that the pie made with regular lime juice wasnt more popular.

To me, this was a perfectly creamy, tart-yet-sweet pie with no astringent aftertaste.

Fresh squeezed key limes!

Six tasters gave this pie top honors for its strong tanginess and clear, tart flavor.

This is the winner because its the most tart, said one taster.

My data says yes!

In fact, regular limes will be my go-to whenever I make key lime pie going forward!
