Whenever coffee or tea is served with cream or sugar and a spoon, especially in a restaurant, it is polite to offer a porcelain saucer to go along with your ceramic and porcelain drinkware. Saucers serve as a resting place for tea bags and spoons after they have been used. They also give the added benefit of serving as a catch for drips or spill-overs. This can help save your guests’ or customers’ garb as well as preventing your tablecloths and tabletops from becoming stained.
For the best presentation, serve matching saucers with your cups. However, if there isn’t a porcelain saucer available that matches your cups and mugs perfectly, just look for one in the same material that is approximately the same color. If you wanted, you could also mix and match the colors of your ceramic and porcelain drinkware instead. Also ensure that the diameter of your saucer is large enough to encompass the bottom of your tea or coffee cup, with room to spare.
