Method...
- Preheat the oven to around 200C/400F/Gas 6.
- Peel the potatoes and chop them into small 0.5cm/¼in piece sticks - a bit thinner than French fries.
- Melt the butter in a saucepan, add the onion and cook until soft. Take care not to burn the onion - it should be cooked, but not turning brown.
- Add the potatoes and cook for a few minutes.
- Layer half of the onion and potato mixture in the bottom of an ovenproof dish, then top with half the anchovies evenly across. Season with salt and pepper.
- Add another layer of onion and potato, then the rest of the anchovies on top. Pour the remaining sprat juice over the dish.
- Add the Essential Cuisine Vegetable Stock Mix to the milk and cream, and pour 2/3 over the dish, then sprinkle the breadcrumbs on top. Season again.
- Bake for about 45 minutes, or until the potatoes are cooked. Halfway through the cooking time, add the rest of the milk and cream. If the dish is looking dry, you can add more milk - the aim is to get a creamy consistency.
- Serve as part of a traditional Swedish smörgåsbord.
