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.
1 Check the potatoes after 5 minutes: Cubed potatoes will cook more quickly than whole potatoes; smaller potatoes will cook more quickly than larger potatoes. 2  Begin checking the potatoes after around 5 minutes of boiling; most potatoes will be done in 10 to 20 minutes. Begin checking the potatoes after around 5 minutes of boiling; most potatoes will be done in 10 to 20 minutes. 2  Potatoes are done when tender: The potatoes are done when they are tender all the way through. 3  You can test this by poking the potato with a fork, paring knife, or skewer.
