This started as an experiment to bring a barbecue feel to my little Paris kitchen. Rubbing meat or vegetables with sweet and savoury spices before roasting or sizzling on a grill is what summer nights are all about. The dry-roasted spices release pervasive aromas, even in an oven, and paired with a crunchy, sweet salad, you have a fine outdoor supper. Don’t be afraid to play with combinations and quantities of spices to create your own bespoke spice rub.
