My ultimate favorite pie is pecan, and look forward to it every thanksgiving. This year, I found out that only a couple people coming like it, so David decided to do pumpkin pie. Thankfully, I had a really great recipe for pecan pie muffins, so I was still able to get my fix in a small dose, while not affecting the larger menu!
While catering for large groups typically means choosing a certain number of entrees and then creating enough for the number of people, you'll almost always have at least someone who has some kind of dietary need: gluten free, vegetarian, vegan, lactose free, etc. Chef Fergy can help you decide if it's better to choose entrees based on those needs, or if it's better to use my "pecan pie muffin" method to create special options for those with dietary needs.
