Here’s how to make the perfect leftover turkey sandwich

Essential knowledge.


Christmas Day means food. The days that follow mean… more food.

Unless you’ve found a way to calculate exactly the amount of food you need for your Christmas dinner, you’re probably still waking up to a fridge bursting with leftovers. It’s a good problem to have.

The undisputed king of the leftover lunch is the turkey sandwich, but how do you go about crafting the perfect sambo? With science, of course!

Greggs, the UK high street bakers, have commissioned a study to find the best way to make a leftover turkey sandwich. Sandwich experts (how do we get that job?) tested dozens of combinations on thousands of volunteers to find the statistically ideal way to make a turkey sambo.

Turkey Sandwich

The research, conducted by Mindlab at the Sussex Innovation Centre, Brighton, found that granary bread, lightly spread with butter, made the ideal base for a turkey sandwich. When it comes to the filling, 25% turkey, 19% stuffing, 14% cranberry sauce, topped with a rasher and a helping of mayo was spot on.

Dr David Lewis, who led the study, said: “The formula is based on the popularity of sandwich ingredients and their association with Christmas, along with taste preferences of respondents and combinations of ingredients that best achieve a multi-sensory experience when you take a bite.”

So there you have it. You can now spend the rest of the day working out the exact percentages required to make the perfect turkey sandwich, because that’s really what the spirit of Christmas is all about.
