Here's a recipe for petit sale (pronounced sallay) using juniper berries in the cure. It's from Jane Grigson's book entitled CHARCUTERIE AND FRENCH PORK COOKERY, page 176:
To every 2 1/2 lb of salt (enough for 12 lb of meat in fact)
1 oz saltpetre (sic)
1 oz granulated sugar
1 tsp peppercorns
1 oz juniper berries
4 bay leaves, crushed
Thyme leaves from two sprigs, crushed
4 cloves
The remainder of the recipe is paraphrased. Rub some of the cure onto both sides of the pork belly. Put about 3/4 lb of the cure into the bottom of a stoneware pot and lay the rubbed belly onto it. Pack the rest of the cure round the sides and over th etop. Cover with a light and sterilised weight. for 4 days minimum and up to much longer, two months in fact.
Once cured, the petit sale can be sliced and parboiled to be served with mashed potatoes, saurkraut or even cabbage. With lentils, in fact.
NB: stoneware and not earthenware is a must (glass is fine, too), since earthenware is porous and its glaze chips too easily compared to stoneware.
