To calculate these costs, you must consider these aspects of the manufacturing environment: Product costing (detailed information) for material, labor, and overhead. Cost reporting (what does the item really cost to produce). Variance reporting (actual versus standard costs).
In a pot, heat water until it boils. Once it boils, add in your potatoes. After about 20 minutes, you can try forking in your potatoes to see how tender it is. Now, another factor on the length of cooking potatoes is how big your potatoes are. Of course, if you use really small potatoes, they will become tender easily.
Roasted potatoes take around 50 minutes to cook. You may need to adjust this cooking time to suit your preferences. As a general rule, the longer you cook the potatoes, the crispier they will be. Of course, overcooking leads to dried out or burned potatoes. Don't forget to allow 10 to 15 minutes to wash, peel and cut the potatoes. For a gas oven, heat it to 350 degrees Fahrenheit for roasted potatoes. The oven should be at the correct temperature before you put the pan of potatoes into it. If you're using a fan oven, set it at 400 F.
