A small onion.
1/3 kilo (depends on the appetites of the diners) of soaked white bean.
1/2 kilo of pork ribs.
2 or 3 thick turnips.
A good bunch of thistles (the frozen ones from supermarkets like Mercadona are great and come clean already).
The onion is poached with very little oil.
Then add the other ingredients and cover it with water, to boil until the beans are tender.
The broth should be thick.
When it is at its point the salt is added and it is given a slight boil.
