Notes & tips.
To bake instead of pan-fry, place patties on a baking tray lined with baking paper. Spray well with olive oil cooking spray. Bake at 180°C for 25 minutes or until golden and cooked through.
When melting butter, chop butter into 1cm pieces. Butter will melt evenly without burning.
Leftover meatloaf or roast meats are also great in these patties. Chop the meat and use instead of the sausages.
