The Filling
Into a bowl, add in corn starch, sugar, soy sauce and white pepper powder. Mix well and then add in minced beef. Mix until well combined, cover the bowl with a cling film and chill in the fridge for 30 minutes.

Heat some oil in a pan on medium high heat. Add in chilled beef and cook until it's fully cooked, breaking it into small pieces as you go. Transfer into a bowl and set aside. Add in grated garlic, ginger and cook until they turn golden

Then add in all the veggies, mix well and continue cooking until they're soft but not soggy. Add in reserved meat together with oyster sauce and mix everything well for a few seconds. Cool completely before using.

Assembling
Prepare the slurry glue by mixing both ingredients together. Set aside.
Take a piece of spring roll sheet and place it in front of you with 1 corner pointing at you. Take 1 tbsp of filling and place it at the bottom corner. Roll tightly until the middle of the sheet. Fold left and right side into the middle at a 90º angle.

Continue folding until almost the end. Paint some slurry glue on the sheet and continue rolling until the end. Place in a tray. Continue with the rest.

Frying
Heat abundance of oil in a pan on medium heat.
Place a few spring rolls at a time into the oil. Fry until golden brown, turning them frequently for even colour. Place them on a plate with kitchen paper to absorb the excess oil. Continue with the rest.

Serve immediately with some sweet chilli sauce on the side.
