Place all the ingredients in a saucepan and set over low heat (3–4 on a scale of 10).
Simmer uncovered for 4–5 hours.
Turn off the heat, lift out the herbs, and discard them.
Transfer the meat and vegetables to a large bowl and shred.
In the pan you’ll see two layers: clear fat on top and dark, intensely flavourful juices underneath. We definitely want to keep those juices!
Set a second bowl nearby. With a ladle, skim as much of the surface fat as you can into it, leaving mostly the juices in the pan.
It’s fine if a little fat remains; pour everything from the pan into the veal bowl and stir to combine. Your rillettes are ready!
Jarring: Have clean jam jars or other airtight containers ready. Layer two tablespoons of rillettes, then one tablespoon of the reserved pure fat, repeating until the jar is full. Finish with a final spoonful of fat.
Seal tightly and refrigerate for up to 2 weeks—or 1 week once opened—unless you’re comfortable sterilising jars, which is another story.
Notes
Salt isn’t an exact science here—especially with all those vegetables—but do stick to 10 g of salt per 1 kg of meat. Any less and the rillettes taste flat; any more and they’re unbearably salty.
