Every time I see my friend Sam, I make a bottle of this for her. We are both obsessed with the stuff – we put it on our breakfast, lunch and dinner! I was heavily influenced here by Ixta Belfrange’s Numbing Oil (from Flavour) and Hetty McKinnon’s Everything Oil from To Asia, With Love. This is my ode to their recipes and to all the other chilli oils I’ve loved before.
