Final answer:
Check the recipe for the correct cooking temperature, as 175°F might be too low for most baking or roasting tasks. If the recipe's temperature is listed in Celsius, convert it correctly to Fahrenheit. High altitude cooking may also require adjustments to both temperature and time.
Step-by-step explanation:
If you notice that your friend has set the oven to 175 degrees Fahrenheit for a recipe from a Mexican cookbook, you would first want to check the recipe to see the recommended cooking temperature. Since common oven temperatures for baking foods like cakes hovers around 350°F and for roasting a chicken around 400°F, it's possible that the set temperature of 175°F is too low for most recipes that require baking or roasting. I would advise your friend to verify the temperature requirement in the recipe and adjust the oven temperature accordingly.
In case the recipe requires a temperature conversion (e.g., if it's listed in Celsius and your friend interpreted it as Fahrenheit), be sure to convert the temperature correctly. You can use the formula (°C × 9/5) + 32 = °F to convert Celsius to Fahrenheit or the reverse (°F - 32) × 5/9 = °C.
If you are at a high altitude, remember that cooking times and temperatures may need to be adjusted since water boils at a lower temperature, which can affect how quickly food cooks.
