I grew up with these Romanian style stuffed peppers and to this day it's one of my favorite dishes ever. Using sweet yellow Hungarian peppers, stuffed with a mixture of ground pork, rice and herbs and slowly cooked in a simple tomato sauce with sour cream.
Arrange a rack in the middle of your oven and preheat to 375 F degrees.
Prepare the peppers by cutting off the tops of the peppers. Remove and discard any seeds and membranes from the insides of the peppers. To keep the peppers from falling over while cooking, cut a small flat piece off the bottom of the pepper so that it has a more even bottom.
In a large bowl combine the ground pork, rice, onion, egg, dill, parsley, salt and pepper. Mix well. Stuff each pepper really well and arrange them in a big pot standing up. I used a large 5 quart oval Dutch Oven with a lid.
To make the sauce whisk together the tomato puree with the sour cream, water, salt and pepper. Pour this over the peppers. Add more water if needed, there should be enough water to come about half way up the peppers.
Cover the pot with a lid or aluminum foil and bake for 1 1/2 hours covered. Remove the lid and continue baking for another 45 minutes to an hour uncovered. The peppers are ready when you insert a fork in a pepper and it goes easy through the skin of the pepper and meat, and the rice is cooked.
Serve these hot with lots of sauce and a dollop of sour cream on top, along side some crusty bread for dipping in the sauce.
These stuffed peppers are best when made with sweet yellow Hungarian peppers or sweet yellow dove bell peppers.
If you do not have tomato puree or passata you can also use tomato paste instead, about 3 or 4 tbsp and just whisk it with enough water to cover the peppers about half way through.
