We blend our own Za'atar, starting by toasting sesame seeds. Once cooled we mix them with sumac, thyme, oregano and salt. You will find our blend contains a high ratio of sumac compared to commercial blends. 
Mix a spoonful of Za'atar with yoghurt to make a dip. Mix with oil and brush onto flatbreads. Sprinkle over roasted potatoes or vegetables.

Here is an easy recipe for Za'atar flatbreads
In a large bowl put 400g bread flour 1tsp salt and 1 tbsp za'atar. 
In a small bowl mix 1tsp fast action yeast, 1 tsp sugar and 200ml warm water. Leave it for 5 minutes.
Once yeast has dissolved pour the wet ingredients into the flour along with 2tbsp olive oil.
Mix together adding a little more water until it all comes together. Tip the dough onto a board and knead for 10 minutes. It should feel smooth and elastic. Put a tsp olive oil in the bowl, turn the dough in it gently to coat then cover with cling film. 
Leave to rise in a warm place until doubled in size.
Knock back the dough and divide into 6. Roll out and cook on the BBQ, plancha or frying pan (No oil) for 3-4 minutes each side until golden. Brush with olive oil, sprinkle over a little more Za'atar and serve warm
