It's particularly useful for finishing dishes like gratins, lasagne, or for toasting bread and pastries. When using the grill function, food typically needs to be placed closer to the heating element. Ensure you select the appropriate grill setting and time, as excessive grilling can lead to burnt surfaces while the interior remains undercooked.
Convection Cooking
Convection cooking utilises a fan to circulate hot air within the oven cavity, promoting even cooking and browning. This mode essentially turns your microwave into a small, efficient conventional oven. It's excellent for baking cakes, biscuits, roasting chicken or vegetables, and achieving a crispy exterior on various dishes. If your Lamona built-in microwave oven features convection, remember that it often requires preheating. The user manual will specify the correct temperature and time required for preheating, much like a standard oven.
Microwave-Convection Combination
This is perhaps the most versatile function, combining the speed of microwave heating with the browning and crisping capabilities of convection. It's perfect for dishes that benefit from both rapid cooking and a desirable texture, such as roasted chicken that cooks quickly but remains tender inside with a crisp skin, or baked goods that achieve a golden-brown finish faster. When using a microwave-convection combination, the appliance intelligently manages both heating methods. Always consult your manual to understand how to select the correct combination setting and cooking duration for different food types.
For combination cooking, always check your manual for the correct cookware. Metal items are often suitable for convection/grill modes but not microwave-only.
