Always begin to measure cooking time after the liquid starts boiling.
Molokhia, Okra, and Taro must be cooked with lemon juice so they don't get slimy.
When buying lemons for their juice buy the heavy ones, when buying them for the zest, choose the clean and yellow ones.
Don't crowd your pan when frying foods. And don't turn the food until it is cooked thoroughly on one side.
