There’s something appealing about receiving a boxful of ingredients with all the spices and loose ingredients measured out for you in little pots and pouches, primed for action. It’s like the wrapped-up neatness of plane food – but without the bland, mass-produced taste and plastic cutlery. How much more appealing if the ready-to-go kit delivers you a healthy meal in less than half an hour (with, okay, a bit of chopping and cooking on your part)?
