Note from Ricardo
For a richer, creamier result, you can replace 1 cup (250 ml) of 3.25% milk with the same quantity of 35% cream. If you don’t have a yogurt maker, at step 3, transfer the yogurt mixture into an 8-cup (2 litre) glass container. Set the glass container in a larger baking dish filled halfway with hot water. Place the container in the middle of the oven without turning on the heat. Turn on the oven light and let sit until the yogurt is set, about 5 hours. Continue with steps 4 and 5.
