Poutine aux raisins is a steamed raisin pudding made in the Acadian area of Canada.
The pudding mixture is made from flour, baking powder, salt, raisins, molasses, egg and water mixed together.
The mixture is placed in a large, clean, empty tin (in lieu of a pudding basin), and then set in a pot on a trivet or something to keep the tin off the bottom of the pot. The pot is then filled with boiling water coming half-way up the side of the tin and covered.
The pudding is steamed for around 1 1/2 hours, then served with a sauce such as a simple caramel sauce.
Older versions would actually put the pudding mixture into a cloth bag, and then the bag into the water. When cooked this way, it becomes one of the many possible recipes for Poutine en Sac.
