So I picked up this interesting ale recently, which advertised itself as "honey and almond." Took one sip and knew it was a perfect posset ale! So I went to the fridge and got the eggnog, thinned it slightly with milk, and heated it in the microwave. Then I poured in the ale (room temp, of course). It frothed up, and drinking it was heaven! Exactly what a posset should be! Think of this as a warm, alcoholic egg cream.
