Eisbein with blueberry relish

Place the eisbeins, star anise, onion, carrot, celery and orange zest in a large pot and cover with water. Simmer for 2½ to 3 hours, or until the meat is very tender.
Remove the eisbeins from the liquid and pat dry.
Preheat the oven to 180°C.
Brush the eisbeins with butter and bake for 15 minutes, until crisp.
Blanch the sugar snap peas and broad beans in boiling water for 2 minutes. Cut the eisbein from the bone and serve with the peas, beans and blueberry relish.
To make the blueberry relish, place all the ingredients in a medium-sized saucepan over a medium heat and simmer until the berries have softened.
