For best results, use a KitchenAid® Stand Mixer and Food Processor Attachment.

Fit the Food Processor Attachment to the Stand Mixer with the slicing disc. Place the mixing bowl under the chute. Select 'thin' and turn to speed 10. Add the onions and chillies and slice

Add the oil to the KitchenAid® Copper Core 3.3L Braising pan. Place the pan over a medium low heat, add the onions and chillies and cook stirring for 5 minutes until the onions glisten and soften

Add the saffron thread mixture and cook 30 seconds. Add the wine, fish stock, tomato paste and season well with the salt and pepper. Bring to the boil, reduce the heat to low and simmer 5 minutes

Increase the heat to high, when the sauce is boiling add the mussels and thyme sprigs. Cover with the lid and cook 3-5 minutes, shaking the pan occasionally, until the mussels steam open

Serve immediately with crusty bread
