Just my opinion, but thats a lot of salt and seasoning for 1 Kg of meat.
Here's a recipe I use.
Pork Butt 1 kg
Salt 15g
Course ground black pepper 4.1g
Fennel seed 6g
Chopped Garlic 6.2g
Crushed Italian hot pepper 5g
And I'm pretty sure this is Kytec Kutas's recipe;
5 tb Salt
1 pt Ice water
1 tb Fennel seed
2 ts Black pepper -- coarse
Grind
1 tb Sugar
3 ts Crushed red pepper flakes
1 t Caraway seed
1 tb Coriander
10 lb Ground pork butts
I'm looking forward to your results with the tomato paste.
