Lara, my girlfriend, asked me if crab would work on a crisp potato rosti and I said of course it would, what a great idea. I demonstrated this dish on the Cob for those of you who watched, so here is the recipe.
2 medium-sized baking potatoes, parboiled in their skins for about 15 minutes, then left to cool
1 small onion, peeled, halved and thinly sliced
Vegetable or corn oil for frying
A good knob of butter
A couple of tablespoons of good-quality mayonnaise
1 small green chilli, finely chopped
Salt and freshly ground white pepper
A handful of small salad leaves and herbs
The brown and white meat from a 700-800g crab
1 lemon, quartered
Remove the skins from the potatoes and grate the potato on the coarse side of a grater. Mix with the sliced onions in a bowl and season.
Heat some vegetable oil in preferably a large, non-stick frying pan. Divide the potato mix into four and place in the pan, shaping into thin, roundish patties with the help of a spatula.
Cook them for 4-5 minutes on each side until crisp, then remove from the pan and keep warm. You may have to do this in a couple of batches, depending on the size of your frying pan.
Mix the brown meat with the mayo and chilli; season. To serve, place the rostis on plates and spoon the brown meat mix into the centre, then arrange the leaves and white meat on top. Serve with lemon.
