He’s the flavour magician who rewrote the shopping list for cooks around the world, from aleppo pepper to za’atar, via black limes, sumac and tahini. A Guardian columnist since 2006, the best-selling, award-winning author of nine books is back soon with more brilliant ideas and recipes in Ottolenghi Test Kitchen: Extra Good Things. Now is your chance to ask Yotam Ottolenghi your burning questions. What are his tips for packing flavour into dishes and what does he cook his family at home? What can you do with harissa butter? What sauces and sprinkles do he and Noor Murad, co-author and head of the OTK, keep in their fridges to add crunch and originality to their meals? Send them your kitchen queries (or anything you’ve always wanted to ask Ottolenghi about his life, food and career) by Friday 29 July.
