Start by pealing off the apple skins, and then slice them into 3-4mm thick slices. Place them in a pot on the stove, on a medium to high heat, adding 2 Tbsp sugar & 125ml's water. Stir and allow to simmer for 5 minutes.
While the apples are simmering, prep the rest of the ingredients. Start by emptying the tin of caramel into a mixing bowl, and add 45ml's of the whipping cream and 1/2 tsp salt to it. Beat with an electric mixer until smooth & creamy.
Empty the remaining whipping cream into a separate mixing bowl, add 2 Tbsp sugar to it and beat until the cream becomes stiff. A good tip is to always ensure that your cream is cold before you beat it. If it isn't, it won't stiffen up nicely and could result in you overmixing it and making butter!
Once the apples have simmered for 5 minutes, add a generous sprinkling of cinnamon (coating the top), stir to coat, and continue to allow them to simmer until all the water has boiled off (about 5-10 minutes).
Using a spatula, place a thin layer of the whipped cream in the bottom of your dish to coat it.
Place the Tennis Biscuits, face down into your dish until the base is covered.
Spread a generous layer of caramel on top of the layer of biscuits (1/2 the amount of caramel).
Remove the apples from the stove once the water has boiled off, allow to cool, and then layer half the apples on top of the caramel layer.
Repeat: cream, biscuits, caramel and apple layers, reserving half of the remaining cream for the top layer.
To finish it off, spread the remaining cream and sprinkle with finely crushed Tennis Biscuits.
Pop it into the fridge and leave it to set for a good couple of hours/over night. This gives the Tennis biscuits a good chance to become soft, and this easy Salted Caramel Apple Cream Tart will melt in your mouth... enjoy!
