Here are some tips: get a screen for the splatter! Don’t cook higher than medium heat. Wipe down the wok after each round of cooking with paper towel. Inevitably you get black burnt bits after each round and those will continue to burn and smoke if you don’t clean it out. If you use the suggested 2TB oil with each batch, most of that will be absorbed by the meat and it won’t be like you’re sopping up tons of oil. You will add new oil for each batch, let it heat up for 30 seconds then add your meat.
Don’t overcrowd your pan with meat! Each piece needs to lay flat.
