Make the base: Crush the biscuits until they look like lumpy sand. (I do mine in a food processor because I'm lazy!)
Mix with the melted butter and press into your 18cm (7") springform pan (US)/loose-bottomed tin.
Whip the cream: Take the cream straight from the fridge (this helps to keep it stable) and whip enough so it holds its shape (to the texture of ice cream). Take care with it - too runny and it will be sloppy, too stiff and it will be too dense.
Make the filling: Combine the whipped cream, icing sugar, cream cheese, lemon juice and half of one tin of caramel (about 200g/7oz). Fold in gently until fully combined.
Assemble the cheesecake: Smooth on top of the biscuit base, dotting the remainder of one of the tins of caramel through it as you go (about 200g/7oz), and flatten the top with the back of a spoon or a palette knife if you have one.
Freeze to set: Pop into the freezer for at least 2 hours or overnight.
Remove the cheesecake from the tin (see notes below).
Pour the rest of the caramel over the top. Sprinkle with the sea salt. For clean slices, dip your knife in hot water and wipe dry between each cut.
