Preparation Steps

• Preheat your oven to 400°F (200°C).
• Wash the sweet potatoes thoroughly. Pierce them several times with a fork.
• Place the sweet potatoes on a baking sheet and bake for 45-60 minutes, or until fork-tender.
• Let the sweet potatoes cool slightly, then slice them in half lengthwise. Scoop out the flesh into a bowl.
• In a saucepan, combine the sweet potato flesh and water. Bring to a simmer over medium heat.
• Cook for about 5-10 minutes, stirring occasionally, until the sweet potatoes are very soft. Mash them with a fork or potato masher.
• For a smoother puree, transfer the mixture to a blender or food processor and blend until smooth. Add the butter and cinnamon, if using, and blend again.
• Serve warm.
