First of all, place your pearl onions into a bowl of water to start to soften the skins.
Meanwhile, take your chuck steak or other stew beef and trim off and discard the excess fat before cutting into roughly 1 inch cubes.
Now begin to preheat your oven to
180 °C. Add the butter to your pan and place it over a medium high heat on the hob, placing your beef inside the pan as the butter starts to melt.
Sear your beef for a few minutes, stirring it with a wooden spoon until it begins to release its juices.
Increase the heat a little and now add your vinegar to the pan.
Stir around for a couple of minutes before adding your garlic, spices and salt and pepper.
Stir those in well and now add your chopped tomato, tomato paste, bay leaf and stock (or hot water).
Stir and cover before placing into your preheated oven for 1 hour.
Meanwhile, you can peel your pearl onions. Cut the tops with sharp knife and peel the skin away, leaving them whole.
Add your olive oil to a frying pan and saute your onions over a high heat for a few minutes until they are taking on colour.
After 1 hour, remove your stew from the oven and give it a stir. Add more liquid if necessary along with your pearl onions.
Cover and place in the oven for a further 60 minutes, reducing the temperature to
160 °C. After one hour, remove your stew from the oven and test the beef to check it is tender.
If it is tender, leave your stew to rest for 30 minutes or so with the lid on before serving.
Serve your soğan yahnisi with crusty bread and / or mashed potato or potato wedges.
