Cut each sheet of spring roll pastry into 9 small sheets.
Put the cut spring roll pastry on a plate and cover (to prevent them becoming dry).
Put some sambal dried shrimp on 1 small sheet, wrap the dried shrimp up, brush the pastry end with some water, seal the spring roll properly.
Preheat cooking oil to 150°C/300°F, put in a piece of spring roll to test the heat of the oil (divide the spring rolls into 3 batches).
Add in 1/3 portion of spring rolls, reduce to medium-low heat, fry for about 6 minutes, stir occasionally so that the heat is evenly distributed. (Reminder: The oil might be hotter when frying the 2nd and 3rd batch. To prevent spring rolls from browning too fast, reduce to low heat for about 1 minute first after adding in the spring rolls, then only increase to medium-low heat.)
After frying for 6 minutes, spring rolls are lightly browned (refer to picture below), turn to medium-high heat, continue frying for about 1 minutes 30 seconds until golden brown before removing from heat.
Put spring rolls on a strainer ladle to strain the oil.
Put the fried spring rolls on kitchen towels to absorb the oil.
Store the sambal dried shrimp spring rolls in an airtight container when they have fully cooled down.
