As a self-described expert in human nature, especially as it relates to butterfat, I do have one suggestion; keep that whole low-fat thing to yourself. This great holiday dessert idea should be able to stand on its own merits, without a disclaimer regarding the reduced calories.
Having said that, if someone's not thrilled with this leaner version, well, then we reserve the right to bust out the old, "hey, what the hell did you expect, I used low-fat milk instead of cream!?"
One note on the recipe quantity: If you use 5 to 6 ounce ramekins like I did, you'll have enough pumpkin flan mixture for about eight. I only did six for the video, so I didn't want anyone to be confused.
