Meals and Laying the Table in Ukraine

The hospitality of Ukrainian people is well-known throughout the world.

When a foreigner sets foot in Ukraine first he gets acquainted with our cookery - national dishes and meal-times. He has to do in Ukraine as the Ukrainians do.The usual meals in Ukraine are breakfast, lunch, dinner and supper. Breakfast is the first meal of the day. Lunch or luncheon is a light meal usually in the middle of the day. Dinner is the chief and the most substantial meal. Working people usually have a break for dinner at their place of employment. If you have a special dinner, you should know how to lay the table on such an occasion.First you spread the table cloth and put out table mats to protect the table from the hot dishes: a plate of soup, a bowl of hot vegetables and etc. Then you put soup spoons and all the cutlery -knives and forks, including a small knife for the butter and a fruit knife for the dessert. You should put the knives and the soup spoon on the right-hand side and the fork on the left. On the left of each guest you put a small plate for bread and on the right - a wine glass. Don't forget to put out the table napkins for each guest and place several salt-cellars. Please don't forget to put a bowl of beautiful flowers on the dinner table. I remember my last receiving the guests. It was my birthday party. We started with hors-d'oeuvres followed by a clear soup with meat pie, the second course included chicken with rice and vegetables and salad. Then ice-cream for the sweet and fruit for dessert. And, of course, I baked a nice cake. All my guests were pleased with my birthday party.
