Long-simmered dishes are just comforting. There aren't a lot of ingredients, but the sauce is delicious. Serve with bread for dipping.
I like beef shank since it becomes tender if you simmer it for a while. I wanted to make a version simmered in beer, but I had white wine so I tried that instead.
If you cook beef shank long and slowly, it will become tender (about 1 hour). If you use a pressure cooker, it's even easier.
