Apparently today is National Kidney Day so here is my contribution...
1 tbsp butter
4 lambs' kidneys, trimmed and cut into chunks
1 tsp Worcestershire sauce
2 tsp tomato purée
2 tsp lemon juice
1 tsp English mustard powder
pinch cayenne pepper
salt and freshly ground black pepper
2 slices white bread, toasted
1 tbsp chopped fresh flatleaf parsley
Heat a frying pan until hot, then add the butter and kidneys and fry for 2-3 minutes, until golden-brown all over.
Place the Worcestershire sauce, tomato purée, lemon juice, mustard powder and cayenne powder into a bowl and whisk together well.
Pour the dressing onto the kidneys and stir well to combine. Cook for a further minute or two, until the kidneys are completely cooked through. Season, to taste, with salt and freshly ground black pepper.
To serve, place the toast onto two plates and top each slice with the kidneys and pan juices. Garnish with flatleaf parsley.
On a more serious note, it really is world Kidney Day and you can find out more information here. Their aim is to raise awareness of the importance of healthy kidneys.
