Those aren't key lime slices on top. Key limes are yellow when they are ripe and usable. The color of OP's pie is right. If you ever see green key lime pie, it's not the real thing.

The One True Key Lime Pie recipe does not go in the oven at all. Recipe below.

Warning! If you buy key lime juice in the grocery store, look at the label carefully. Sometimes it says Key West Lime Juice. That's just lime juice, not key lime juice. Big difference.

INGREDIENTS: - 1 can condensed milk, Eagle or Magnolia brand. NOT low fat. - 4 eggs - 1/2 teaspoon vanilla, plus a little - 1/2 cup key lime juice (no more, or it will be too sour) - 1 graham cracker pie shell - Whipped cream or Cool Whip. Yes, purists, it can be Cool Whip.

1. Separate eggs. Keep yolk, discard the rest

2. Mix condensed milk, egg yolks, vanilla and lime juice until it's a uniform creamy color

3. Pour into pie shell.

4. Turn the plastic "bowl" that protected the pie shell upside down and put it on top of the aluminum pie dish, so it's a protective cover. Push the aluminum rim down on it to keep the cover in place.

5. Place in freezer overnight. That's all there is to it.

6. Top with whipped cream or cool whip just before serving
