This oil-as-sauce was first put together for the root vegetable and couscous pilaff. The pilaff is flavoured with the complex but low-key tastes of our chermoula so we came up with this oil to add a dramatic element to the mix. It’s a combination I love: sweet, rich and very hot. It’s hard to say how many this recipe serves, but it makes 600 mls. Depending on the chilli-heat level and your fondness for it, this could feed eight to fifteen people. I like it to be very hot in which case a little gives a big hit, but if you make it a bit milder it’s a pleasure to mop up loads of it. Up to you. The finished oil will keep very well for up to a week in a fridge.
