First of all, grind your peppercorns and cumin seeds in a pestle and mortar.
Now, except for your mixed vegetable filling and the sauce, add all of your dalyan kofte ingredients to a mixing bowl, breaking your raw egg over the top.
Mix and knead the mixture for a couple of minutes, adding a small splash of water as you go so that you have a soft, pliable meat mixture.
Bring all the mixture together into a rough elongated substantial köfte shape and place onto a sheet of baking/parchment paper.
Form an oval shape and make an indentation along the centre so that it resembles a dinghy boat.
Pour your mixed vegetables into the 'boat' and then bring the sides of the meatloaf together so that you make a roll, concealing the vegetables inside.
Preheat your oven to
200 °C Now roll the parchment paper around your dalyan köfte so that it is parcelled and tuck the ends in. Roll this in a second sheet and, again, tuck the ends in.
Place your parcelled Turkish meatloaf onto an oven tray or rimmed baking sheet and put into the centre of your oven and leave to bake for 45 minutes.
Meanwhile, you can make your tomato paste, ketchup and olive oil mixture. Mix these together and add a splash of water to loosen it. You need enough sauce to spread over the top and around the sides of your meatloaf.
After 45 minutes, remove your meatloaf from the oven and carefully remove the parchment paper.
Spread your sauce over the top and around the edges of the meat and place the meatloaf back into the oven - uncovered - for a further 15 minutes.
After this time, remove your dalyan köfte from the oven and leave to rest for around 10 minutes.
Either serve whole and a centrepiece for the table or cut it into thick slices for individual servings.
Enjoy with further mixed vegetables, mashed potatoes or salad.
