C
The correct answer
The correct answer is B: 12.
Why is 12 the correct answer?
Well, if you remember from your school days, according to the order of operations, you do multiplication before addition and subtraction, so you start by solving 3 x 3, which results in 9.
Then we are left with a simpler math problem: 3 + 9 – 3 + 3
The answer is therefore 12.

A Brief History
The vintage sandwich toaster, also known as a pie iron or jaffle iron, has an intriguing history that dates back to the early 20th century. The first known patents for these devices appeared in the United States and Australia in the 1920s and 1930s. Originally designed for camping, these cast iron devices allowed users to cook hot, sealed sandwiches over an open fire. By the mid-20th century, electric sandwich toasters became popular household appliances, bringing the convenience of toasted sandwiches indoors.
Usage: A Culinary Revolution
The primary function of a vintage sandwich toaster is to create hot, sealed sandwiches by pressing and toasting bread with various fillings. The process is simple: place a buttered slice of bread on one side of the toaster, add fillings such as cheese, ham, or even fruit, and then cover with another buttered slice. Close the toaster, clamp it shut, and cook over a heat source or plug in the electric version.
Outdoor Cooking
In camping settings, the cast iron pie irons were placed directly into the fire or on a camp stove, making them versatile for outdoor cooking.
Home Kitchens
As electric models gained popularity, they brought the same versatility into home kitchens. These appliances allowed for a quick, convenient way to prepare meals, making them a favorite among busy families.
Legacy: More Than Just a Kitchen Gadget
The vintage sandwich toaster holds a special place in culinary history. It represents a time when kitchen gadgets began to prioritize convenience and efficiency. In the post-war era, as families sought quicker meal solutions, the sandwich toaster became a symbol of modern domestic life.
Nostalgia and Collecting
Collectors and nostalgia enthusiasts often seek out vintage models, appreciating their durability and retro charm. These devices evoke memories of childhood for many, recalling simple yet satisfying meals made with care.
Modern Influence and Resurgence
Today, the legacy of the vintage sandwich toaster lives on. While modern versions have evolved with non-stick coatings and more sophisticated designs, the core concept remains the same. The resurgence of interest in retro and vintage kitchenware has also revived the popularity of these classic appliances.
Return to Simplicity
In a world where convenience foods are often processed and less wholesome, the sandwich toaster offers a return to simple, homemade meals. It encourages creativity in the kitchen, allowing users to experiment with different ingredients and flavors. Moreover, it fosters a sense of nostalgia, connecting us to the culinary traditions of past generations.
Conclusion
The vintage sandwich toaster is more than just a kitchen gadget; it’s a piece of history that highlights the evolution of home cooking. From its origins in outdoor camping to becoming a household staple, it has remained a beloved tool for creating quick, delicious meals. Its legacy continues as modern iterations and a renewed appreciation for vintage kitchenware keep the spirit of the sandwich toaster alive. Whether used for a classic cheese toastie or an innovative new recipe, this humble appliance endures as a symbol of culinary simplicity and ingenuity.
