Andrew Blake is a talented restaurateur from Australia, and this recipe is from his magnificent book published some years ago called Blakes - and demonstrates a wonderful yet simple combination of ingredients.
Sweat the onion and garlic in a little olive oil for 2 minutes on a medium heat. Cool and place in a mixing bowl with the minced venison and pork fat, sage and eggs; mix well and season.
Form into 4 large patties, about 2-3cm thick.
In a heavy based frying pan, cook the venison patties in a little olive oil to a medium-rare stage.
