Bring 3 cups water and sugar to a boil, stir until dissolved.
Combine remaining cold water and cornstarch until smooth, add to boiling syrup and cook and stir until thickened and clear. Stir in gelatin powder until dissolved.
Cool slightly until room temp but still pourable and use for fresh strawberry pie, tarts, eclairs, cream puffs, etc. Makes enough for at least 2 pies. Leftover glaze can be stored in the refrigerator for a few days, just warm in the microwave until pourable to make another pie or more tarts.
NOTES : You can also use other flavors of gelatin for other fresh fruit pies; such as peach, raspberry, etc.
