1Peel and boil the potatoes until they are tender. This should take about 15-20 minutes.
Once cooked, drain the potatoes and mash them until smooth.
In a small saucepan, melt the butter over low heat.
Add the mashed potatoes to the melted butter and stir well to combine.
Zest the lemon and add the zest to the potato mixture.
Cut the lemon in half and squeeze the juice into the mixture, ensuring no seeds are included.
Add the sugar and vanilla extract to the mixture and stir until everything is well combined.
Cook the mixture over low heat for an additional 5 minutes, stirring occasionally.
Remove from heat and let it cool slightly before serving.
Serve warm or at room temperature as a unique dessert.
