3 large parsnips, peeled and trimmed
2 large potatoes, peeled and quartered
4 cloves garlic
⅓ cup milk
Salt flakes and freshly ground black pepper, to taste
75g butter
4 x 180g Ocean Perch fillets, skin on
1 tablespoon extra virgin olive oil
30g blanched almonds, roughly chopped
4 large green olives, pitted and roughly chopped
2 tablespoons French tarragon leaves, chopped
1 lemon, zested

Place the potatoes, parsnips and garlic in a saucepan, cover with cold water, bring to the boil and cook for about 10 minutes, until tender. Drain thoroughly, mash, and pass through a fine sieve to remove the stringy parsnip core. Stir in the milk, salt, pepper and two-thirds of the butter. Set aside and keep warm until needed.

Score the skin of each fillet, making several lengthways cuts around 5mm deep. Brush with olive oil and sprinkle with salt and pepper.

Heat a heavy-based frying pan over a moderately high heat and add fillets, skin side down, in a single layer. Cook for about 3 minutes, until the skin is crisp and well-coloured, then turn and cook the other side for 1-2 minutes, until flesh flakes easily when tested with a fork. Remove to a warm plate.

Melt remaining butter in the frying pan, add the almonds, salt and pepper and stir for 1-2 minutes, until almonds start to colour. Stir in the olives, tarragon and lemon zest.

Place a dollop of the parsnip mash onto each serving plate, rest a fillet on top and spoon the almond mixture over the top.
