It's refreshing with vinegar and whets your appetite.The allysine compound from the onion helps the absorption of Vitamin B1 from the pork, and helps recovery from exhaustion. It also increases your stamina.
I added onions to the recipe "Refreshing with vinegar and great for recovering from summer exhaustion! Pork stamina stir-fry," and modified the recipe to help recovery.
Stir-frying with onion adds a little bit of sweetness to the dish.If you want more vinegar flavour, add as needed when plating.
Enjoy Japanese food around the world.
