Some chefs spend a lot of time in the kitchen trying to ensure their dishes look beautiful before the food reaches the table. Although sight is not technically part of taste, it certainly influences the diner's perception on the food being served.
At home, you don't have to be a professional chef to make your meals as visually appealing as they are tasty. The way the food is presented is what tempts our eyes and make us want to taste it. So yes! Food appearance and presentation is important.
When you are plating the food, red and yellow are the chief food colours, evoking the tastebuds and stimulating the appetite. Both red and yellow are also effective in grabbing diner's attention. If you don't have red or yellow, orange usually does the trick too. Other colour like green is also good in creating the contrast and elevating the presentation.
So, allow yourself the freedom to be creative, and let yourself fall in love with dishing up healthy meals that are feast for the eyes!
