Whisk together the yogurt and lemon curd in a large bowl, then slowly whisk in the lightly whipped cream.
To hand freeze, pour the mixture into a freezer box and freeze for 5 - 6 hours, removing from the freezer and whisking every 1 1/2 - 2 hrs with a balloon whisk or hand electric mixer.
If using an ice-cream maker, pour the mixture into the bowl of the machine and churn until thick and almost frozen.
When nearly frozen either in the freezer or ice-cream maker, fold in the broken cookies, return to the freezer until needed
It is advisable to give the ice-cream 15 - 30 minutes in a fridge before you serve it to soften up.
