First make the crust. If you haven't already, pulse graham crackers, salt and sugar in a food processor until finely ground. Add melted butter and press into a tart pan. It is beneficial to have a tart pan with a removal bottom. Press so crust is even on bottom and sides. Bake at 350 degrees F for 10 minutes or until crust firms up.
Make the cheesecake. In a bowl, mix together the cream cheese, sugar, egg, lilikoi juice and salt using a stand or hand held mixer. Mix until everything is combined and fluffy.
When crust is done, remove from oven and allow to rest for a few minutes. Pour in cheesecake mixture and continue to bake at 350 degrees F for about 35 minutes or until the cheesecake is firm but still has a slight giggle to it.
While cheesecake is baking, make the glaze.
In a small pot, add water and sugar and allow to boil for 5 minutes until the sugar dissolves. Add lemon juice and lilikoi juice and continue to boil for another 3-4 minutes until it turns into a thick syrup. Remove from heat.
When cheesecake is done, remove it from the oven and pour the lilikoi syrup all over the cheesecake.
Allow cheesecake to cool at room temperature before cutting into it.
