Add more water to the pot where the hocks were simmering earlier and increase the heat to high. Skim off any foam and discard it.
When it starts boiling, add the meat from the pork hocks as well as the meatballs - if the liquid cools off too much, place the lid on to bring it back to a boil.
Sift the remaining toasted flour over the pot by adding a little bit at a time and stir well between each addition. The amount of flour added depends on how thick you want your gravy, you can always add more later during the cooking time – I normally go for about 4 to 5 cups.
Reduce the heat to a simmer and let it cook for 3 hours, stirring often - as the ragoût cooks, the sauce will thicken.
After an hour of cooking, taste and adjust the seasoning.
Another half an hour later, start boiling water in a medium pot. Add pork sausages and boil them for about 10 to 12 minutes.
When time is up, remove them from the heat and gently scrape the casings off; discard them.
Add the sausages to the ragoût and let them simmer for the remaining 1 hour.
When the 3 hours is finally up, taste and adjust the seasoning by adding salt, pepper and mixed spice.
