Traditional Key Lime Pie

I have been making this pie for many years. Every time that i serve it, people say

Beat egg yolks.

Stir in sweetened condensed milk , key lime juice and rind.

In a small bowl , stiffly beat 1 egg white.

Fold into pie mixture.

Turn into baked pie shell.

Beat the three reserved egg whites with cream of tartar until foamy.

Gradually add sugar , beating until stiff but not dry.

Spread meringue on top of pie , sealing carefully to the edge of the pie shell.

Bake 15 minutes at 350 or until meringue is golden brown.

Cool in refrigerator at least 6 hours.
