I want to make the Cornbread Topped Chilli for 30 people for my daughter's wedding. Will it turn out ok if I use one and a half times the ingredients or should I just double the quantities? Many thanks, Dawn
Nigella's Cornbread Topped Chilli Con Carne (from Feast and on the Nigella website) is enough to feed up to 20 people. However portion sizes can depend on the appetite of your guests, as well as what other dishes you may be serving. For such an event it is best not to be under-catered and we favour erring on the generous side and making a double quanity if this is the only main dish. If you are offering a buffet with several other dishes then a 1 1/2 quantity should suffice.
For convenience you may find it easier to serve the chilli with some cornbread muffins rather than having a cornbread topping. If you prefer this option then you could make Nigella's Cornbread-On-The-Cob recipe from Nigella Bites (p133). The recipe makes 12 portions so you could make 3 batches to cover your 30 guests. The recipe can also be made into regular muffins or in a 20cm (8-inch) square pan. This would also have the advantage that you could make the cornbread on the morning of the wedding, leaving you only the chilli to reheat before the wedding feast.
