Rinse chicken wings and wipe dry. Chop them into chunks and blend in marinade. Fry wings briefly for later use.
Shell shallots, rinse well and saute briefly, remove and drain excess fat.
Heat earthen pot and add 1 1/2 tbsp oil, saute ginger slices and preserved black beans. Put in chicken wings and shallots. Splash wine and pour in seasonings. Bring ingredients to boil, then lower heat and simmer till chicken wings are done. When sauce gets thick, garnish with spring onion sections and serve hot in pot.
