Cook pumpkin in a little water until soft. Drain well and mash. Stir in remaining ingredients to combine.
Heat oil in a deep saucepan. Drop in tablespoonfuls of mixture and deep-fry until golden all over. Alternatively you can fry them in a frying pan (but the fritters won’t puff up as much). Drain on paper towel.
Serve drenched in syrup and/or sprinkled with cinnamon sugar and a squeeze of lemon juice.
