BIRCHER MUESLI
Source: Texas Monthly

The recipe for this delicious muesli was published in the Australian Gourmet Traveller, in 1994, at the request of a reader who had enjoyed it at one of the Holiday Inn hotels. This is our adaptation, which we love to have as a treat on Sunday mornings.

3 cups rolled oats
3/4 cup fresh orange juice
1 1/3 cups milk (you can use low-fat or soy if preferred)
2 tablespoons sugar
2 tablespoons honey
1/2 cup plain yogurt
1/2 teaspoon vanilla essence
1/4 cup sultanas
1/2 cup light cream (for whipping)
2 tablespoons slivered almonds
1 to 2 granny smith apples, peeled and grated (optional)
ground nutmeg or cinnamon (optional)
1 to 2 cups mixed fresh fruit, peeled and diced (such as raspberries, strawberries, melon, apple, banana, grapes, Kiwi fruit, pineapple, mango)

In a large bowl, combine the rolled oats, orange juice, milk, sugar, honey, yoghurt, vanilla essence and sultanas.

Mix well, cover, and either refrigerate or leave in a cool place overnight.
The next morning, whip the cream, and fold it through the muesli with the slivered almonds (and grated apple if desired).

If the consistency is firmer than you prefer, add more milk or cream to taste.
Sprinkle with cinnamon or nutmeg (optional).

Serve with fresh fruit.
