Ah, the humble sandwich – a staple in lunchboxes and picnic baskets across Australia and indeed the world. But what elevates a sandwich from simply sustenance to a culinary delight? In celebration of National Sandwich Day, food scientists have finally cracked the code to create the perfect sandwich, and the findings might just surprise you.


The art of sandwich-making has evolved significantly since the 18th century when John Montagu, the 4th Earl of Sandwich, reportedly invented it to eat without interrupting his card game. Today, the sandwich is a canvas for creativity and a reflection of personal taste, yet there are some universal truths to making a truly great one.


Firstly, let's talk about the bread—the foundation of any sandwich. The experts suggest a robust variety like sourdough, wholegrain, or brown bread. These types hold up better and won't get squashed or soggy, which is crucial for a satisfying sandwich experience. What is the ideal thickness? About 0.7 inches (2cm) perfectly balances durability and digestibility.


Now, onto the spread. Real butter is the champion here, and it should be spread right to the edges of the bread. Not only does this add a rich, creamy taste, but it also creates a moisture barrier to keep your sandwich from becoming a soggy mess. Room temperature butter is best for easy spreading without tearing the bread.

When it comes to the filling, symmetry and strategy are key. A double-folded meat layer adds texture and protects against any potential sogginess from wetter ingredients. Cheese, with its fat content, further fortifies this barrier.

But what about the veggies? Salad elements like lettuce, gherkin, or onion provide that essential crunch – a sensory delight that enhances the eating experience. However, the tomato poses a risk with its high water content. The solution? Dehydrated tomatoes. This innovative approach retains the flavour without the sogginess, ensuring your sandwich remains intact and delicious.


Construction is just as important as the ingredients. Lay your bread side by side and build your sandwich in layers, placing the wetter components in the centre, insulated from the bread. This method not only prevents sogginess but also ensures every bite is balanced and full of flavour.

Colour is another consideration. Vibrant hues make a sandwich more appealing, so don't shy away from adding various colours. This not only pleases the eye but can also enhance the overall taste experience.

And while it may be tempting to pile on the fillings, restraint is advised. Overloading can lead to structural integrity issues, and nobody wants their sandwich to fall apart mid-bite. The goal is to create a sandwich that's easy to hold and eat without any fillings escaping.


Finally, the sandwich should be visually appealing. Let those fillings peek out a bit – it's not just about taste but also the allure of what you're about to enjoy.

So, dear members of the Seniors Discount Club, remember these tips from the food scientists next time you're in the kitchen. Whether you're a fan of the classic ham and cheese or something more gourmet, the perfect sandwich is within reach. It's all about the right ingredients, the right construction, and a little bit of love.
