Mix soy sauce, sherry, mango juice, vinegar, mustard
, ginger, and garlic
together in a bowl. Reserve 1/3 of the mixture for a glaze. Put abalone
steaks in a shallow baking dish
, pour marinade
over. Marinate the steaks for at least 30 minutes or refrigerate covered up to 4 hours.
Preheat an outdoor grill to high heat.
Put the reserved marinade in a saucepan
in the brown sugar and cornstarch. Simmer
over low heat until marinade thickens to create a glaze. Set side but keep warm.
Place 2 skewers about 2 inches apart on your work surface. Weave the marinated abalone steaks onto the skewers so that the steaks will lie flat on the grill
. Alternate with fruit pieces between the steaks. Each double skewer
will hold 2 to 3 steaks plus fruit.
Grill over high heat until abalone is cooked, about 1 minute per side. Brush the fruit with the glaze
and serve immediately.
