Here's my take on granola. I have been making this for more than 10 years.
9 cups large oat flakes
3 cups barley flakes
2 cups rye flakes
2 cups spelt flakes
2 cups wheat flakes
The grains are mixed and put in the oven at 350 degrees. Stir every 20 to 30 minutes; roast until golden brown - about 3 hours.
Add:
2 cups roasted cashew pieces (unsalted)
2 cups roasted sunflower seeds (unsalted)
1.5 cups slivered almonds, toasted to a light golden brown
1 cup roasted pumpkin seeds (unsalted)
1 cup pecan pieces
This makes us enough for about a month.
Half a cup of this granola is enough for a breakfast serving. I eat it with fruit (usually bananas and blueberries) and milk, but it is great with yogurt too.
