Read the text and mark the statements T (true), F (false) or DS (doesn’t say).

Like its neighbour, the USA, Canada celebrates Thanksgiving with a traditional roast turkey dinner. Canadians celebrate Thanksgiving on the second Monday in October. It’s not as big a celebration as the one in the USA but it’s very similar in many ways.

The centre piece of the table is always a large roast turkey. The turkey is often stuffed with a mixture of bread crumbs, onions, sausage meat and sage. Sometimes, the stuffing is cooked separately too. Most people spread butter all over the turkey, place it in a large metal tray, cover it in foil and then roast for several hours in the oven. Once the turkey is cooked it is put on a serving plate to cool and the cooking juices are used to make gravy. To make the gravy, add flour and chicken stock to the cooking juices from the turkey and stir constantly while the mixture is over a low heat. Bring to boil and keep stirring until the gravy becomes thick. When it’s ready, pour it over the turkey and the vegetables, which traditionally include roasted potatoes, mashed sweet potatoes, parsnips and carrots.

Another suggestion is to serve the turkey with cranberry sauce. After the meal, tradition says that guests enjoy a slice of pumpkin pie for dessert.
