Cooking appliances vary. These instructions are given only as a guide.
Make sure that the food is piping hot throughout before serving.
Place pizza on a baking tray and cook in a pre-heated oven at 200°C, 400°F, Gas Mark 6 for 12-20 minutes.
The pizza is handmade and so probably doesn't conform to a precise shape or thickness - but 12 to 20 minutes? An instruction such as "cook until the cheese melts and starts to brown" would be more useful (to anyone unsure of how to cook pizza, that is).
