What's the product?

Tortillas, made in Kensal Green from freshly ground white and blue masa harina corn by a machine that goes by the name El Monstruo. They'll add an authentic Mexican edge to your next taco night. Did we mention they're naturally gluten-free, too? Oh yes.

Who makes it?

Dodie Miller started selling dried Mexican chillies from a little market stall on Portobello Road in 1993. Local interest soon piqued and Miller and her team began to create salsas, sauces and pastes and moved over to big ol' Borough. But salsa needs a vessel to transport that sweet spice into your mouth; so in 2005, when they realised that fresh corn tortillas were hard to come by in the capital, Miller and her team decided to make their own.

What do they taste like?

The foundation of a great taco lies in its base. And with these tortillas, you're onto a winner. On the toasted side of nutty, with a rich, lingering smell of baked corn, just slap on some chipotle and guac and they're good to go.

Where can I get them?

You can find Cool Chile Co at Borough Market from Thursday to Saturday – or check out coolchile.co.uk. The 'cook at home' tortillas come in blue or white and in four different sizes, starting at £1.75 for a pack of ten.
