In Merry Olde English days of yore, a posset was a drink made from hot milk laced with ale or wine and spiced. It was popular in the Middle Ages as a remedy for colds and minor ailments and a sleep-aid. Posset appeared in Shakespeare's Lady Macbeth knock out the guards outside Duncan's quarters with a poisoned posset.
Using just three ingredients, it seems almost magical, and sets up almost immediately. The wonders of food science in front of your very eyes make this a quickest, easiest dessert, like ever. Curdled cream becomes a thickened cream dessert; similar to lemon curd or key lime pie.
1 cup heavy cream
1/3 cup sugar
Juice of one medium lemon
Nutmeg (optional)
Remove the cream mixture from the heat and stir in lemon juice. Let the posset cool for about 10 minutes before pouring into ramekins. This custard is very rich, so I recommend using smaller dishes. I used these proportions (which makes two nice servings) because I only had 1 cup of cream, but the recipe can be very easily doubled, tripled, etc.
Refrigerate until set. Depending on how thick you want the pudding, it may take up to 2 hours. Top with a sparse grating of nutmeg (sounds a bit odd, but it’s quite a good match). It is traditional to serve with shortbread cookies, but sadly I found none in the pantry.
