How We Calculate Conversions (Methodology)
At KitchenMetric, we prioritize food safety and accuracy. Our Air Fryer algorithm converts standard oven temperatures by reducing heat by 25°F (approx. 15°C) and cooking time by 20%. This accounts for the rapid convection airflow in modern fryers.
For baking, we utilize standard density weights (e.g., 1 Cup AP Flour = 120g). We recommend using a digital scale for the most accurate results, as volume measurements can vary by humidity and packing method.
Understanding Air Fryer Logic
Air fryers are essentially powerful convection ovens in a small package. Because the fan circulates hot air rapidly around the food, heat transfer is much more efficient than in a traditional still-air oven. Failing to reduce the temperature often results in the "burnt outside, frozen inside" phenomenon.
Instant Pot Liquid Ratios
The "Burn" error is the enemy of every pressure cook user. When converting recipes for the Instant Pot, remember that there is almost no evaporation. If a stove-top stew calls for 4 cups of stock, you may only need 2 cups in the pressure cooker. Always ensure you have at least 1 cup of clear liquid at the bottom to generate steam.
