Pan-Fried Cod with Chillied Anchovies

This is my new approach to cooking and presenting a cod fillet (though you can make it with other firm-fleshed white fish, such as halibut or haddock, with equally good results). Although this way of cooking fish with onions and chillies is typical of my homeland in West Sumatra, the finished dish is quite unlike anything that I ate when I was a child. It would normally have been deep-fried or barbecued, there would have been many more chillies and the anchovies used would be dried ones. Yo
