Notes
Rump steak, top sirloin, round steaks, flank steak, or skirt steak are all perfect for this recipe. The thinly sliced sizzle steaks are also good choices.
Baking soda is also known as bicarb of soda, bicarbonate of soda, and sodium bicarbonate. Don't get it muddled with baking powder!
You can use regular all-purpose soy if you don't have light soy sauce.
We like to do a mixture of colors here. Red and Green look pretty with the yellow pineapple, but you can use any color peppers.
Just regular tomato ketchup, the kind you would have with your French fries. (Called tomato sauce in Australia)
Feel free to use white sugar instead.
Chinese Cooking Wine is also known as Chinese Rice Wine, Shaohsing Rice Cooking Wine, Shaoxing Wine, or Shaoxing Cooking Wine. You can find it in most grocery stores in the Asian section, on Amazon, or in your local Asian grocery store. Use dry sherry or sake if you can't find Chinese Cooking Wine.
Use canned pineapple chunks that come in juice, not syrup. This is because the juice is used in the sauce. I prefer to buy the chunks as they are the biggest; I don't go for pineapple tidbits (USA) or pineapple pieces (AU), as they are smaller and are more prone to fall apart in the sauce. The can size of pineapple differs from country to country; go for a can that is about 17oz-20oz/435g-550g.
Baking soda is amazing at tenderizing meat, but it doesn't taste very good, so make sure you rinse the beef several times.
