When Sanjay Aggarwal and his mum Shashi decided to sell spice tins (masala dabbas) as a retirement project for Shashi, they had no idea that it would grow into a thriving premium spice business. I caught up with Sanjay to hear how they have slowly grown the business into Spice Kitchen UK, their extensive range and we (well, me!) do some geeking out over za'atar!
