Add remaining 1 cup water, Plant Butter, sugar and salt to medium saucepan and bring to a boil over medium heat. Add flour, reduce heat to medium-low and cook, stirring constantly, about 3 minutes or until mixture comes together and is smooth.
Be sure to monitor the oil temperature. If the temperature drops too low, churros will not form properly. If it gets too high, churros will brown too much. Don't overcrowd the pot. Fry 4 to 5 churros at one time.
A thinner star tip will give a crisper churro. The number of churros will vary with the size of the star tip and the length of the churro.
