Boston Bread

Preparation:

Preparation: In a large bowl, sift the three types of flour with the bicarbonate of soda and salt in a large bowl. Add the molasses, yogurt and raisins. Mix well. From the mixture obtained, obtain three equal parts. Put each part in a previously buttered 500 g round coffee tin. Cover each box with wax paper followed by aluminum foil. Make sure you leave some space (about 3 cm) between the box and the paper, to allow the bread to rise. Secure the sheets with string. At this point, place the boxes on a net that you will place in a very large pot. Fill the pot with boiling water until it covers 3/4 of the boxes. Bring the water to the boil, cover the pot with a lid, lower the heat and cook in a bain-marie for 2 and a half hours. Check the pan from time to time and, if necessary, add enough water to reach the original level. After the necessary time, gently remove the boxes from the pot. Let cool just enough to remove the pieces of bread from the boxes. Serve hot with butter.
