Combine liquids in a large pot and heat but do not boil.
Mix the oats, wheat germ, sunflower seeds, walnuts, and almonds in a large bowl and slowly pour the dry mix into the hot liquid. Stir with a large spoon to combine well and then pour the mixture into a large roasting pan and place in the oven. Toast the mixture for 1 hour, stirring often to prevent burning.
Remove from the oven and add the raisins. Allow to cool throughly before transferring to an airtight storage container. This will keep for 4 weeks when properly stored.
