Your beef should look like this. If you are using beef chunks, you will be required to cook them for a longer period.
Marinate them with some vinegar, soy sauce, garlic powder, chili powder, black pepper (whatever spices you have). Let them sit aside for a few minutes. Some people will coat them with corn flour or all-purpose flour at this stage.
Pour about 2 tbs of oil or butter in a heated pan. Place the marinated pieces but do not overcrowd them. Let them brown evenly on each side. It takes about 6-9 minutes
In the meantime, prepare your vegetables
Once well-browned, take your meat out of the pan. Add your garlic and onion in the same pan. Add a little oil if need be.Let the onion saute till translucent
Add in your vegetables, some salt(not too much since we have soy sauce), and black pepper(to give some spicy taste). Give it a good mix. Stir your sugar in about 1/4 cup of water and 1 tsp of cornflour. Add in your beef and cover it with the sugar-cornflour mixture. Gently mix everything well and let it simmer for about 10 minutes.
Once ready, garnish with some spring onion and parsley. Serve with your preferred starch
Some recipes will call for pineapple, honey, or ketchup to create the sweetening effect. Use the same recipe to recreate sweet and sour pork and chicken recipes
