Line a loaf tin with enough foil to cover the base and extend over two sides.
Blend ricotta and sugar until smooth.
Whisk cream to soft peaks.
Combine ricotta, nougat and nuts. Gently fold in cream. Add raspberries and fold through the mixture.
Put the mixture into the prepared tin, ensure it is covered in foil and freeze until firm. Before serving, slice, and allow it to soften slightly in the fridge.If using ice-cream, it doesn't hurt to double-line the tin firstly with foil and then with cling film, wrapping your "loaf" first in film, then in foil before re-freezing. Serve by itself, with fresh berries, or coulis For coulis, combine frozen raspberries, sugar and water over a low heat, mixing to ensure sugar dissolves completely and raspberries break down. Push through sieve if you can bothered.
