Roast Tomato and Chili Salsa/Sardines Escabeche

No Mexican worth their salt would ever sit down to eat without some salsa at hand, so this episode's first course is Tommi's roast tomato and chilli salsa. In Mexico City, Tommi visits a street-food stall that has been delivering the goods for over thirty years. Back in her kitchen, Tommi claims to have a recipe that will make the humble sardine sexy.
