Marinate the pork for 10 minutes, meanwhile prepare the breadcrumbs and mix the sauce
Dip the pork pieces in the breadcrumbs then in oil at about 160 degrees (a wooden spoon makes small bubbles when you put it in). Fry until barely golden.
Once all the pieces are fried, fry them a second time until golden. Set aside.
In a wok, over medium-high heat, sauté the spring onions and ginger for 1 minute in a little oil. Then add the well-mixed sauce and stir until nicely thickened.
