The atmosphere at my parents' house already feels like a solstice celebration, it's always cozy and softly lit, there's usually a fire going, there are often candles flickering. We spent almost every evening playing cards by the fire, which is what I usually associate with solstice celebrations. This night, we played Uno. To make it feel like an extra celebratory evening, we had a flaming coffee/hot chocolate for dessert.
First, Grandpa makes a sugared rim by dipping the sugared edges into the flame.
Otto was a big fan of the sugared rim. He may request that all future drinks have this feature.
