Lemon and cava sorbet

PREPARATION
Option 1: Empty the content of the Brik directly into
your slush-sorbet maker, add 2 litres of water and
1 bottle of cava. Turn on your slush-sorbet maker
and the sorbet will be ready in approx. 30 minutes.

Option 2: The same process as option 1, but add
2 litres of milk instead of 2 litres of water.
