Spike's Apple Sorbet

First of all, chop the apples into ½ inch (1 cm) cubes and place them in a food processor, along with the lime juice, membrillo (or jam), sugar and Calvados, and process everything to a fine purée.

Now set a large, fine nylon sieve over an equally large bowl and pour the puréed mixture through it, pushing it with the back of a spoon to get as much apple pulp through as possible. All that should be left in the sieve are the tiny flecks of apple peel, which can be discarded. Now you need to be fairly swift or the apple will discolour. Pour the mixture into the ice-cream maker and freeze-churn. This may take a little longer than usual, due to the generous quantity of alcohol.

Either serve straightaway or spoon it into the plastic box and freeze for later. From the freezer, it will need 20 minutes in the fridge to soften before serving.

NOTE:
If you don't have an ice-cream maker, you can still make ice cream.

After you have made up your mixture, transfer it to a lidded plastic box and put it in the coldest part of the freezer for two hours, or until the contents become firm at the edges. At this stage, empty out the box into a mixing bowl and whisk the ice cream with an electric hand whisk to break down the ice crystals. Return the box to the freezer for another two hours, then repeat the whisking process. Refreeze the ice cream (if making a sorbet that contains a generous quantity of alcohol, as Spike's Apple Sorbet does, freeze overnight) until 30-45 minutes before you want to serve it, at which time you should transfer it to the fridge to soften.
