Step 1

Dry-roast cumin seeds in a small frying pan until fragrant (30 seconds to 1 minute), then crush with a mortar and pestle to a fine powder. Process cumin with soaked sunflowers seeds and garlic in a blender to a coarse paste, then add remaining ingredients except herbs and process, gradually adding a little water (about 100ml) until smooth. Transfer to a bowl, season to taste and refrigerate to chill (2 hours).

Step 2

Stir herbs into dip, top with extra oil and sunflower seeds and serve with crudités.
