Method

1. 1
   First make Onion, Apple and Leek Relish: Add all the relish ingredients (Onion, apples, chilli sauce, vinegar, sugar and leeks) to a large pan. Cover the pan and cook on a reduced heat until the leeks are soft and the apples fluffy, approx 10-15 minutes. Meanwhile make the patties.
2. 2
   In a bowl place lamb mince, mint jelly and onion. Season well and mix together thoroughly.
3. 3
   Divide into 8 and shape into patties.
4. 4
   Cook under a preheated grill for 8-12 minutes until cooked through.
5. 5
   Remove relish from heat and serve either hot or cold. (Alternatively, if you are short on time buy a relish to serve with the patties). Serve patties with relish and griddled Welsh cakes.
6. 6
   Serve on floured buns with salad.
