In key lime pie do you use green food coloring?

While green food coloring is sometimes used in key lime pie, it's not essential and isn't a traditional ingredient.

Here's why:

* Natural Color: Key lime juice itself has a pale yellow-green hue.

* Filling Texture: The filling is typically quite dense and opaque, so the green color is often masked.

* Taste: Green food coloring adds no flavor, and some consider it unnecessary or even detracts from the natural beauty of the pie.

If you want to use green food coloring:

* Use a small amount to achieve a subtle color.

* Start with a few drops and add more gradually until you reach your desired shade.

* Be cautious as it can make the filling too green.

Ultimately, whether or not you use green food coloring is a matter of personal preference.
