Soak raisins in your choice of liquid for about an hour
Prepare the custard by whisking the sugar & cornstarch together in a medium sauce pot then add the plant milk & optional tumeric for color, whisking constantly over medium to high heat until it comes to a boil.
Once it boil for 10 seconds remove from the heat & add the vanilla extract
Pour the custard into a heatproof container or glass bowl & refrigerate until cold & set.
Peel & core the apples then slice them into ¼" thick slices
Preheat the oven to 400°F on convection setting or 425°F on regular setting
Unfold the 2 sheets of puff pastry & place on a parchment lined sheet pan then cut along the creases making 6 separate rectangles *see video visual
2 of the rectangles will become the base to build the french apple tarts & the other 2 rectangles will get cut into 8 equal strips longways equal to the length of the base puff pastry rectangles *see video
With a small amount of vegan egg wash brush lightly the edges of the puff pastry rectangles then carefully place the strips as a border for each one
You will end up with 4 rectangles or French apple tarts total
Spoon the vanilla custard into the center of each rectangle of puff pastry ~careful not to get any on the border strips
Arrange the apple slices along the custard then sprinkle with the drained, soaked raisins if using
Brush the entire pastry & the apples with the egg wash & bake immediately in the preheated oven for about 25- 30 minutes or until the pastry is golden browned and puffed up to the max!
Meanwhile combine the apricot jelly with the water in a small sauce pot &whisk over medium heat until the jelly has melted & it is to a glaze consistency
Once the French Apple Tarts are finished baking brush them gently with the apricot glaze to seal the fruit & give it a beautiful shine
Cut each pastry into 4 servings or whatever portion size you like, then serve immediately or store according to the notes section below
