1 baked pie shell (9")
1 1/4 c. sugar
6 tbsp. cornstarch
2 c. water
1/3 c. lemon juice
3 eggs, separated
3 tbsp. butter
1 1/2 tsp. lemon extract
2 tsp. vinegar

Mix sugar and cornstarch together in top of double boiler. Add water. Combine egg yolks with juice and beat. Add to rest of mixture. Cook until thick over boiling water for 25 minutes (this does away with starch taste). Add lemon extract, butter and vinegar; stir thoroughly. Pour into pie shell and let cool. Top with meringue and brown in oven.
