we're having a potluck this friday with the theme being comfort/soul food. I'm in charge of dessert but i have no idea what to make. There's going to be around 15 people and i was maybe thinking of creme brulee or a cheesecake. I dont have 15 individual ramekins but i do have a really huge one, maybe 12 inches in diameter. Would that be enough? Any other ideas? I want to avoid desserts that are best served warm.
