Roasting as a technique doesn't only apply to meat.
The process of roasting is about caramelising natural sugars in an all-encompassing heat source. It is a classically Anglo cooking method and one we inherited as colonials - hence our familiarity with it.
1. Skin and hollow out your medium sized onions with a melon baller or small knife.
2. Stuff with a mixture that you have blitzed in your food processor - ginger nut biscuits, toasted cashews, bread crumbs and a bit of butter or oil.
3. Sit the stuffed onions on a baking dish and after sprinkling with more breadcrumbs dot each onion with butter. Add a cup of water to the dish.
