Heat the oven to 180C/160C fan/gas 4. Toast the walnuts until dark and fragrant, about 7-10 mins, taking care not to burn them. Allow to cool, then chop finely.

Peel, core and finely chop the apples. Mix with the cinnamon, lemon juice, silan (date syrup), orange zest, sweet wine or grape juice and salt. Add the cooled nuts and stir again to combine. Transfer it to a closed container and keep chilled.
