How to Make It
Bring water to a boil in a saucepan; add grits and salt, and return to a boil. Cover, reduce heat to low, and cook, stirring occasionally, 5 minutes. Remove from heat.
Process grits, pineapple, and cream cheese in a blender until smooth. With blender running, add eggs, 1 at a time. Add sugar, milk, and vanilla; process until smooth. Pour into crusts.
Bake at 300° for 1 hour or until centers are set; cool on a wire rack.
