Boulets à la liégeoise

Liège meatballs in sweet and sour sauce

Big, tender pork and beef meatballs simmered in a glossy onion sauce sweetened with Liège's dark apple and pear syrup and sharpened with vinegar.

Boulets à la liégeoise

Liège, the nearest city to Spa, is proudest of its boulets: two or three fat meatballs of pork and beef in a dark, sticky, sweet and sour sauce. The secret is sirop de Liège, a thick black syrup of cooked down apples and pears that locals spread on bread and stir into everything. The sauce is often called sauce lapin, rabbit sauce, because it was first made for rabbit; the rabbits, presumably, approve of the change.

Every brasserie in Liège serves boulets frites, and they are the obvious dish for a Belgian Grand Prix weekend: generous, comforting, made in one pot, and happy to be reheated when you return damp from the Ardennes. Serve them with fries, as Liège does, and a cold beer.

The meatballs

Ingredients

Method

  1. Tear the bread into the small bowl, pour over the milk and leave for 5 minutes. Squeeze lightly and crumble it.
  2. Put the pork, beef, soaked bread, egg, onion, parsley, salt, pepper and nutmeg in the large bowl and mix with your hand for 1 to 2 minutes, squeezing it through your fingers.
  3. With wet hands, divide into 8 portions and roll each into a smooth, firm ball about 2 1/2 inches (6 cm) across.
  4. Heat the butter and oil in the skillet over medium heat. Brown the meatballs for 8 to 10 minutes, turning them every 2 minutes with the tongs. They do not need to be cooked through yet. Lift them onto a plate.

The Liège sauce

Ingredients

Method

  1. Add the butter to the same skillet over medium heat. Add the onions and cook for 12 to 15 minutes, stirring and scraping up the browned bits from the meatballs.
  2. Sprinkle in the flour and brown sugar and stir for 2 minutes. Pour in the stock gradually, stirring constantly so no lumps form.
  3. Stir in the sirop de Liège, vinegar, bay leaves, thyme, cloves, raisins and crumbled biscuits. Bring to a simmer.
  4. Return the meatballs and their juices to the pan, turning them to coat. Cover and simmer gently over low heat for 25 to 30 minutes, turning the meatballs halfway.
  5. Remove the bay leaves, thyme stalks and cloves. Taste the sauce: it should be clearly sweet and sour. Add a splash of vinegar if too sweet, or a little more syrup if too sharp. If the sauce is thin, simmer uncovered for 5 minutes.
