Ingredients
1 onion, finely chopped
2 sticks celery, finely chopped
500g (0.6 lb) ground beef
2 glasses water
1 tin tomato paste
1 cup chicken stock
3 sprigs of rosemary
Instructions:
Soften the onion and celery in a large saucepan.
Mix good beef (loosen with a splash of olive oil).
Add the meat in small batches and brown, make sure you’ve got plenty of space in the saucepan or the meat will boil rather than brown and caramelize.
Add water and reduce to half on medium heat.
Add the stock, rosemary and tomato paste and cover and simmer for 2 – 2 1/2 hours until the sauce becomes rich and thick.
Serve over freshly cooked pasta so that the pasta will absorb the yummy juices.
Grate some parmesan and pepper.
