Please choose the correct ending to complete the given sentence: Food and Entertaining: [header] How to make sweet potato mash [title] Peel and cut the sweet potatoes. [step] Use a vegetable peeler to remove the skin from the sweet potatoes, then rinse the bare sweet potatoes with running water. Cut each one into 2-inch (5-cm) chunks.

Ending1: [substeps] Since you'll be removing the skins from the sweet potatoes, there's no need to scrub them clean beforehand. A simple rinse after peeling the spuds should be enough to remove any residual dirt from the flesh. Ending2: [substeps] The meat of the sweet potatoes will work best for this recipe. Do not use russet potatoes, as these are not sweet enough for this sweet potato mash to beat the grater. Ending3: [substeps] The potato skins are vital for making sweet potato mash-all you need is room to spare. Make sure you remove the rind (the dark flesh) from each sweet potato before cooking them. Ending4: [substeps] If you don't have two sweet potatoes, you can use a potato peeler to remove most of the skin, which is preferable. Also, cut each sweet potato into wedges if you're making a sweet potato mash, as their bitter pear flesh will make the mash much sweeter.
