Bring to a boil. Cover, reduce heat & simmer for 2 hours, checking occasionally.

After 2 hours, stir in potatoes, carrots & celery and bring to a boil. Cover & simmer 10-15 minutes until vegetables are done.

Combine flour with 1/4 cup stock or water, whisking until there are no lumps. Stir into stew and cook 5 more minutes until thickened.
