1 tbsp. lime flavored gelatin
1/4 c. water
1/2 c. warm water
1 c. + 2 tbsp. non-fat dry milk powder
1/2 c. sugar
1/2 c. fresh lime juice (about 4 limes)

Sprinkle the gelatin on the 1/4 cup water to soften.

Mix the milk powder into the 1/2 cup warm water. Heat to steaming (40 to 50 seconds in microwave). Stir in gelatin and sugar to dissolve. Cool until thickened.

Add lime juice to milk mixture and stir well. Beat egg whites until stiff and fold into lime mixture. Pour into 9" cracker crumb crust. Refrigerate until ready to serve.
