Equipment

  • If you have an air-fryer you could use it to cook the lamb as long as you have a small pan to fit the air-fryer, otherwise a lidded frypan.

Method
 

  1. Assemble ingredients
  2. In a bowl prepare the marinade by combining the first thirteen ingredients
  3. Add the lamb to the bowl and coat with the marinade. Cover and refrigerate for 4 – 6 hours
  4. Closer to the time you want to eat, cook the sweet potato in a small lidded saucepan with one cup of water and salt.
  5. Simmer the sweet potato with the lid on until the sweet potato is tender – about 20 minutes
  6. Remove the lid and let it simmer for about another 5 minutes to reduce the liquid
  7. Test the sweet potato to make sure it is thoroughly cooked. Take off heat
  8. Add the white wine vinegar, honey, butter and ground white pepper
  9. Mash with a fork, stick blender or whisk. Check seasoning. Keep warm
Cooking the lamb:
  1. Drain the lamb, reserve the marinade
  2. In your frypan, over medium heat, seal the lamb on all sides – there should be no need for extra oil
  3. When the lamb is nicely sealed pour in all of the marinade and lid the frypan.
  4. Slowly cook the lamb to your liking – 20 mins to well done if that’s the way you like it or less
  5. Take the lamb out and rest it on a plate. Take the pan off the heat
Assembly:
  1. Meanwhile add the rocket leaves, walnuts, E.V.O. and balsamic vinegar in a bowl and lightly toss
  2. Return the frypan to a medium heat adding any collected meat juices to the cooking residue
  3. On two warm plates place a generous serving of the mash
  4. Slice each lamb rump into two or three pieces
  5. Arrange the lamb on top of the mash
  6. Divide the pan juices evenly between the two portions
  7. Top with the rocket salad
  8. Sprinkle with a little black pepper
  9. Ready

Notes

Marinating for 4 – 6 hours is probably best, but can be overnight in the fridge
The mash works well pre done as well and re-heat in your microwave is OK
Lamb back strap is also a good cut for this recipe
