Tip : If you cannot find Hungarian white peppers, you could substitute Cubanelle peppers or bell peppers in a pinch, but honestly, the best and only pepper for this recipe is the Hungarian white pepper.
Pour 1/3 cup basmati rice in small sauce pan and add enough water to barely cover and bring to boil.
The rice should be cooked about half way. When you see craters on the surface and the water seems to have mostly evaporated, remove from heat and allow to cool to room temperature.
Prepare 4 Hungarian white peppers for stuffing by cutting off the tops and then removing the ribs, keeping the peppers whole.
When the rice has reached room temperature, place 1 lb ground pork, 1/2 tsp ground black pepper, 1/2 tsp Hungarian sweet paprika, 2 1/2 tbsp finely chopped onion and the parboiled rice in a small bowl and combine using a kneading motion with your hands.
Sauce
Heat 1 1/2 tbsp oil in medium sized wide stock pot. Add 1 1/2 tbsp all-purpose flour and stir until the flour is smooth, about 2-3 minutes.
Remove pan from heat and add 1 1/2 cups tomato sauce and stir with a wire whisk to combine and remove any lumps.
Slowly add 1 cup of water and continue to stir until the sauce begins to thicken.
Reduce to a simmer adding a 1/2 onion peeled and half of a tomato (optional) and any trimmings from the peppers.
Final Preparation
Stuff peppers and make small meat balls with any remaining stuffing mixture.
Gently lower peppers and the meat balls into the tomato sauce and bring to a boil.
Reduce heat to a gentle simmer, cover with a lid propped open with a wooden spoon and cook for 30-40 minutes or until the pepper skins look soft. Scrape the bottom of the pan to loosen the peppers periodically.
Add 1-2 tbsp sugar to the sauce just before serving.
Serving
Slice peppers and center on a plate, drizzle with tomato sauce and surround peppers with more sauce
