Stir the sugar, water, lemon juice, and lemon zest in a saucepan and bring to a boil over medium heat.
Reduce the heat to low and simmer for 15-20 minutes until slightly thickened. Remove from heat and stir in the vanilla extract.
Cool to room temperature and then cool completely in the fridge.
Fruit Salad
Put all of the fruit in a large bowl, pour the chilled glaze over it, and stir to combine. Cover an store in the fridge.

Notes
Storage: If you mix the glaze into the salad, it will last 1-2 days in the fridge. The cut-up fruit will last 2-3 days in the fridge without the glaze.Recipe adapted from Pioneer Woman.
