Metric Kitchen: Culinary Temperature

Food temperature is key to a successful recipe. For example, too high of a temperature may cause outer edges to burn while the inside remains uncooked. Cooking, refrigerator, and freezer thermometers are essential kitchen measurement tools. Cooking foods to appropriate temperatures eliminates harmful bacteria that cause illness and food poisoning. Food that is left at room temperature (20 °C to 22 °C) for an extended time creates a suitable environment for microbial growth.  According to the FDA, bacteria can multiply at temperatures between (1 °C to 52 °C). Chilling food slows bacterial growth and decreases the risk of foodborne illness. Understanding your oven temperature is a baking best practice! Each oven, although similarly manufactured, will have temperature differences. When working with heat sources in the kitchen, use hot-pad holders or thermal gloves.
