Method

• Combine the water and sugar and stir over low heat, without boiling, until dissolved. Simmer for 5 mins.
• Add mint leaves and lime juice and vanilla, and simmer further 2 mins.
• Let steep and infuse for 1 hour.
• Once cooled, blitz with stick blender adding xanthum gum until it thickens slightly (this just helps with mouth-feel and is not a necessary component).
• Beat egg whites until soft peaks form, fold completely into sugar mix.
• Allow to cool in refrigerator.
• Put in ice cream churner until it reaches desired consistency.
