In a medium saucepan, combine water, sugar, salt and butter.
1 cup (240ml) water, 1 tbsp sugar, ¼ tsp salt, 6 tbsp (85g) butter
Bring to a gentle boil over medium heat, stirring until the butter is completely melted.
Reduce the heat to low.
Add the all-purpose flour all at once.
1 cup (120g) all-purpose flour
Stir vigorously with a wooden spoon or a whisk until the mixture forms a smooth ball and pulls away from the sides of the pan, about 1–2 minutes.
Remove the pan from the heat and cool the dough slightly.
Let the dough cool for 5 minutes so the eggs do not cook when added.
Transfer the cooled dough into a stand mixer bowl fitted with the paddle attachment.
Mix on low speed for 1–2 minutes to cool and smooth out the dough.
Add 1 tsp vanilla extract and mix until combined.
1 tsp vanilla extract
Add eggs one at a time, mixing well after each addition.
3 eggs
Continue mixing until fully incorporated and smooth.
Continue mixing until the dough becomes smooth, glossy and silky.
The dough should be soft and pipeable, similar to thick custard, not stiff.
Heat the oil in a deep pan.
Vegetable oil
Pour 2–3 cups of vegetable oil into a deep pot or heavy-bottomed pan.
Heat the oil to 175°C to 180°C.
