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.
I prefer steaming the potatoes. The amount of time required to boil potatoes depends on the size and cut. Potatoes that are boiled whole typically take 20-30 minutes. You can reduce the cooking time by cutting the potato into cubes, which usually cook in 10 minutes. To determine if your potato is thorough boiled, poke them gently with a fork. The fork will easily penetrate the potato when it is cooked completely through.
