Article in English: Remove your potatoes from the freezer. Place them in their airtight container directly into your refrigerator. Let them sit for 1-2 days before cooking them. This gives them time to defrost. If you only want to defrost a small amount of potatoes, remove them from the airtight container and place them in a separate airtight container for defrosting. Put the potatoes into a pot over medium-high heat. Stir the potatoes occasionally as they cook. Then, add additional ingredients or garnishes, as desired.  You can also heat the potatoes in a covered dish in the oven at 350 °F (177 °C) for about 30 minutes. To cook them in a microwave, heat them at half power for about 5 minutes. Check them, then heat on high in 30 second intervals until they’re warm. Spread the frozen fries out on your greased baking sheet. Then, put them into the preheated oven for 20-25 minutes. Flip them about halfway through baking.  Eat the fries while they’re warm. Cooked fries only need to heat for about 5-15 minutes. Check them often to make sure they don’t burn.
