Preheat your oven to 375°F and prepare a baking sheet by lining it with parchment paper.
In a large bowl, beat the eggs and granulated sugar until the mixture is thick and pale.
Blend in the pumpkin puree and lemon juice until the mixture is smooth and well combined.
Sift the flour, ginger, salt, baking powder, and cinnamon together. Gently fold into the pumpkin mixture.
Spread the batter evenly onto the prepared baking sheet and sprinkle with chopped pecans.
Bake for 13 to 15 minutes, or until the cake springs back when touched. Allow it to cool slightly, then roll it up in the parchment paper to shape.
