These emojis depict ready-made food. The page contains a lot of street and fast food, like hamburger, shawarma, pizza, hot dog. You can also see home-cooked meals: scrambled eggs, casserole, soup, meat appetizers.
Are you an adventurous chef or a daring cook? Then this emoji set will be suitable for you. For instance, when you get a question 「what are you going to cook today?」, you can always reply with one of these emojis. I wish Unicode had such emojis as burnt meat and mushy bread for this purpose.
