Beef Smitane with Grated Chilli Fries

1 Heat a large frying pan. Finely chop the onion. Add 1 tbsp oil to the pan and cook the onion for 2-3 minutes until softened, stirring occasionally. 2 Place the beef in a bowl with the tomato ketchup, Worcestershire sauce, egg, mixed herbs and plenty of seasoning. Tip in the cooked onion and mix until well combined. 3 Return the frying pan to the heat and using slightly wetted hands, shape the beef mixture into four patties. 4 Brush the pan with a little more oil and cook the beef patties for 4-5 minutes on each side for medium to well done. Set aside on a warm plate to rest. 5 Grate the black pepper into the bottom of a small pan. Add the vinegar and cook until reduced to almost nothing. Heat a deep-fat fryer or 5cm/2" oil in a wok to 190C/375F. 6 Slice the gherkins. Add most of them to the reduced vinegar mix, (reserving some for a garnish) with the cream and mustard seeds. Cook down gently until slightly reduced and thickened. 7 Season to taste and stir in any juices from the rested beef patties. Cut the potato into julienne strips or coarsely grate by hand or in a food processor. 8 Rinse well under cold running water then place in a tea towel to squeeze out the excess moisture and then pat dry on kitchen paper. 9 For the Dressing: Place the remaining tbsp of vinegar in a small bowl. Add the seasoning, stir until dissolved and whisk in 4 tbsp sunflower oil. Reserve some whole chives for garnish, snip up the rest and whisk into the dressing. 10 To test that the oil is ready, add a bread cube - it should bubble and float on the surface almost immediately. 11 Fry the potatoes in batches, if necessary for a few seconds until crisp and golden brown. 12 Remove the fries with a slotted spoon and drain on kitchen paper. Mix together the chilli powder and a heaped tsp of salt and use to season the fries. 13 Place the salad leaves in a bowl and season generously. Pour over the dressing and toss to coat. 14 Stir any juices from the burgers into the sauce. Arrange a burger on a serving plate and spoon over some of the sauce. Garnish with the reserved gherkin slices and some whole chives. Add a mound of the seasoned chilli fries and some salad. Serve at once. Recipe by: Anything You Can Cook
