Add the tennis biscuits and melted butter to a food processor and process until it resembles fine breadcrumbs
In a large bowl whip the fresh cream and sugar just until it's slightly thick. Add in the cottage cheese, a little at a time and beat until smooth
Add in the condensed milk and lemon juice and mix well
Using a trifle bowl sprinkle 1/3 of the crumbled tennis biscuit at the bottom, gently pat it down a little with your hands. Spread 2&1/4 cup of the cheese mixture on top
Sprinkle another layer of tennis biscuits on top of the cheese mixture
Spread another 2&1/2 cup cheese mixture on top
Repeat. Final layer will be the cheese mixture.
To decorate, whip the half cup fresh cream and pipe on top. Sprinkle some lemon rind over and refrigerate
