Whenever I make these biscuits, my guests are always intrigued — the results are buttery with a delicate salty-sweet flavour which plays with your taste buds

Method: 

• Using a stand mixer with a K blade, mix together the butter and olive oil at medium speed for 2–3 minutes, scraping the sides as you do so.
• Add in the fine and coarse salt, icing sugar and sugar and mix briefly.
• Add in the flour, cornflour and herbs. Mix until the ingredients come together to form a soft dough. Wrap and chill for 3 hours.
• Preheat the oven to 180°C.
• Place half of the chilled dough on a floured sheet of baking parchment and flatten to 5mm (around 1/4 in) thickness. Using a knife, cut the dough into 7 x 3cm (2 ½ x 1 ¼ in) rectangles.
• At this stage the dough is very soft, so transfer the rectangles, still on the baking parchment on a tray, to the freezer for 15 minutes.
• Repeat the process with the remaining dough.
• Line two large baking trays with parchment. Transfer the chilled biscuits to these large lined baking trays, making sure to space them well apart.
• Lightly brush each biscuit with water and sprinkle over coarse sea salt and za’atar.
• Bake the biscuits (in batches if need be) for around 15 minutes, until the edges are golden.
• Cool and store in airtight containers, where they will keep for at least a week.
