Via the Amateur Gourmet, homemade mayonnaise:
Look at that creamy, dreamy concoction. Even the me of yesteryear might have to dip my finger in to taste. I think anyone who hates mayo should make it themselves; seeing how it works--how the oil emulsifies with the egg yolk and the lemon juice--makes all the difference.
I've had a similar mayonnaise reawakening: when I was younger, I absolutely hated mayonnaise, to the point that thinking about it made me gag. A couple of years ago, though, I started making homemade mayonnaise, and I never looked back. It's delicious, and fun.
(It still feels kind of gross to dip a spoon into mayonnaise and taste it, though.)
