Как правильно читается напишите по русски! (не перевод) Спасибо сразу!
1. The recipe was invented in a St Petersburg cooking competition in the 1890s. It won the first prize and was named after the Stroganov family, whom the cook was working for. This dish traditionally consists of beef, onions, mushrooms and sour cream.
2. The dish originates from the Caucasus. No picnic or outdoor party can do without this wonderful dish. It's meat marinated in herbs, onions and wine. Then the meat is put on skewers and cooked on an open fire.
3. It's a really delicious, small round bread. Bread used to be the most important food in Russia, and no dish was eaten without it. That's why bread is still so important to people in Russia. They used to decorate it with leaves and flowers.
4. Traditionally, mothers-in-law bake these for their sons-in-law at Easter, and they also used to be made for poor people and pilgrims. They should be thin, brown, and round and look like little suns. They are usually eaten with sour cream, jam, cheese and black or red caviar.
5. These are a favourite Russian dish. They are made of dough and meat and then they can be frozen and kept in the fridge for a long time. They are served with butter, sour cream, vinegar or tomato ketchup. You can buy them in the shops too, but the ones you buy can't be compared with the real homemade version.
6. It's one of the most popular dishes in Russia. The recipe — was created at the end of the 18th century. It's a kind of soup, which got its name from its main ingredient — beetroot. Nowadays it's made with cabbage, potatoes, carrots, tomatoes and meat. On hot summer days it's even better with no meat in it, just vegetables, fresh cucumbers, eggs, onions and greens.
