Hello zuzu, I've finally gotten around to getting my hands on the Atkin's book with the flan recipe in it. Sorry it took so long...here it is.

Flan

5 eggs
1 cup heavy cream
1 cup water
5 packets of Equal or equivalent
1 capful almond extract
dash nutmeg or dash cinnamon

Preheat oven to 350 degrees. Whip first five ingredients in blender for 3-4 minutes. Pour into large baking dish or individual dishes and sprinkle top with nutmeg or cinnamon. In oven set in larger pan half-filled with water. Bake for 40 minutes or until set at 350 degrees.

Total grams: 15.5
Grams per serving 3.9

(I added the 1 c. unsweetened coconut right after the first 5 ingredients were beaten.) I thought it was pretty good!

This recipe is on p. 412 of Dr. Atkins' New Diet Revolution.
