Avocado lime ice

Put the sugar in a pot over heat, dribble in the water and whisk from time to time until it boils and the sugar has dissolved.

Let the syrup cool completely.

Juice a few limes.

Scrape the soft avocado flesh out and mash it down, pulsing in the blender, to measure three cups of pulp.

Combine the lime juice, the cooled sugar syrup and a big pinch of salt with the avocado and blend until smooth.

Run the mixture in a frozen bowl ice cream maker about half an hour, until as thick as soft-serve.

Scoop into a dish and freeze until firm.
