Bring 250 ml water, saffron threads, cumin, cinnamon, cayenne pepper and 1/2 teaspoon salt to the boil in a covered pot. Remove from the heat, stir in the couscous and let it swell covered for about 5 minutes.
Stir several times with a fork.
In the meantime roughly chop the walnuts. Heat 1 tablespoon of olive oil in a pan, roast the walnuts in it over medium heat while turning, remove. Wash the mint, shake dry and pluck the leaves from the stalks.
Put the couscous from the pot into a bowl. Let it cool down for about 15 minutes, stirring several times. Mix in lemon juice and 6-7 tbsp. olive oil. Mix in cherries and mint leaves. Season again with salt, pepper and sugar.
Leave to stand for about 30 minutes. Arrange on a plate, crumble goat's cheese over it.
