Cut your apples into small chunks. Place in a small pot and add the brown sugar, water, cinnamon and vanilla. Cook over medium heat, covered, for about 5 minutes. Remove from heat.
3 medium apples, peeled and cored, 3 tbsp brown sugar, 2 tbsp water, ½ tsp cinnamon, ½ tsp vanilla
In a large pot combine the milk, Jotis vanilla pudding, butter, sugar and vanilla powder.
1½ liters milk, 8 tbsp Jotis vanilla pudding mix, ⅔ cup sugar, 3 tbsp butter, ½ tsp vanilla powder
In a small bowl whisk together the eggs so that the yolks and eggs whites are well combined. Add into the pot with the milk.
7 large eggs
Bring the heat up to medium and cook your custard for approximately 10 minutes or until thickened. After 8 minutes or so, add in the cooked apples and all the liquid in the pot. Continue to stir constantly with a whisk for a few more minutes (for a total of about 10 minutes). It is important to whisk constantly during this time to prevent the custard from burning.
Once your custard is thickened, pour it over the syrup-soaked kataifi. Spread it evenly over the kataifi. Place in the refrigerator for at least 2 to 3 hours until the custard is set. See Recipe Note.
