When it comes to crafting the perfect Reuben sandwich, debates rage on about the ideal temperature for its star ingredient: sauerkraut. Should it be served hot, or is cold the way to go? In this comprehensive article, we’ll delve into the world of fermented cabbage, exploring the history, benefits, and culinary implications of sauerkraut on a Reuben. Buckle up, folks, as we embark on a journey to settle the age-old question: is sauerkraut hot or cold on a Reuben?
A Brief History of Sauerkraut and the Reuben Sandwich
Before we dive into the great sauerkraut temperature debate, let’s take a step back and appreciate the rich history behind this tangy condiment and its iconic sandwich partner. Sauerkraut, a fermented cabbage dish, has its roots in ancient Europe, where it was first produced in the 4th century BC. German and Dutch immigrants brought their fermentation techniques to the United States, where it became a staple in many households.
Fast-forward to the early 20th century, when Corned beef and sauerkraut were married in a harmonious union, giving birth to the Reuben sandwich. This mouthwatering creation is often attributed to Arnold Reuben, a German-American restaurateur, who served it at his New York City deli in the 1920s. The Reuben swiftly gained popularity, becoming a beloved classic in the culinary world.
The Science Behind Sauerkraut’s Flavor and Texture
To better understand the implications of temperature on sauerkraut, let’s explore its flavor and texture profiles. Sauerkraut is made by fermenting finely shredded cabbage in its own juice, typically with the help of salt and caraway seeds. This process creates a multitude of beneficial compounds, including:
- Lactic acid bacteria: responsible for the tangy, slightly sour taste and the fermentation process itself
- Volatile compounds: contributing to the pungent aroma and flavor
- Enzymes:** breaking down the cabbage’s cellular structure, resulting in a softer, more palatable texture
When sauerkraut is exposed to heat, these compounds undergo significant changes:
- Flavor profile:** heat can enhance the sweetness and reduce the sourness, making the sauerkraut taste milder
- Texture:** heat causes the cabbage to soften further, potentially becoming mushy or overcooked
On the other hand, when sauerkraut is kept cold, its natural flavor and texture are preserved:
- Flavor profile:** the tangy, sour taste remains more pronounced, and the volatile compounds are better retained
- Texture:** the cold temperature helps maintain a satisfying crunch and firmness
The Case for Cold Sauerkraut on a Reuben
Proponents of cold sauerkraut on a Reuben argue that it provides a delightful contrast to the warm corned beef and toast. By keeping the sauerkraut chilled, its natural flavor and texture are preserved, allowing it to shine as a distinct component of the sandwich. Cold sauerkraut also helps to:
- Cut the richness:** of the corned beef and melted Swiss cheese, creating a well-balanced flavor profile
- Add crunch:** providing a satisfying textural contrast to the soft bread and meat
The Deli Counter Argument
Many deli owners and enthusiasts swear by the cold sauerkraut approach, as it allows the flavors to meld together beautifully. When building a Reuben, the cold sauerkraut acts as a refreshing contrast to the warm, savory ingredients. This harmony of temperatures and flavors creates a memorable eating experience.
The Case for Hot Sauerkraut on a Reuben
On the flip side, those in favor of hot sauerkraut on a Reuben argue that it enhances the overall flavor and texture of the sandwich. By warming the sauerkraut, it:
- Intensifies flavors:** the heat releases and enhances the umami flavors, complementing the corned beef and cheese
- Softens the cabbage:** making it easier to integrate with the other ingredients, creating a cohesive, indulgent experience
The Comfort Food Angle
Hot sauerkraut enthusiasts often cite the comforting, homely aspect of a warm Reuben. The soft, slightly sweet sauerkraut adds to the sandwich’s cozy, indulgent nature, making it a perfect comfort food option.
The Compromise: Warming Sauerkraut to Room Temperature
What about finding common ground between the two camps? Warming sauerkraut to room temperature (around 68°F to 72°F or 20°C to 22°C) offers a compromise:
- Preserves natural flavors:** while still allowing the flavors to meld together and the texture to soften slightly
- Enhances aroma:** the sauerkraut’s pungent aroma is released, adding to the overall appeal of the sandwich
This approach provides a happy medium, as the sauerkraut is neither too cold nor too hot, allowing its natural characteristics to shine while still complementing the other ingredients.
Expert Opinions and Regional Variations
We reached out to experts in the culinary world to gather their thoughts on the ideal temperature for sauerkraut on a Reuben:
- Chef John Mitzewich (American Culinary Federation): “I prefer my sauerkraut at room temperature, as it allows the flavors to integrate without overpowering the other ingredients.”
- Sandwich aficionado, Jeff Mandell: “Cold sauerkraut is the only way to go. It provides a beautiful contrast to the warm corned beef and adds a satisfying crunch.”
- NYC-based deli owner, Rachel Diamond: “We serve our sauerkraut at room temperature, but some customers do request it hot. Ultimately, it comes down to personal preference.”
Regional variations also play a role in the sauerkraut temperature debate. In some parts of Europe, particularly Germany and Austria, sauerkraut is often served warm or even hot as a side dish. In the United States, the deli-style Reuben typically features cold sauerkraut.
Conclusion: Embracing the Sauerkraut Temperature Spectrum
The sauerkraut temperature debate is far from being a binary issue. Rather, it’s a nuanced discussion that highlights the versatility of this incredible ingredient. Whether you prefer your sauerkraut hot, cold, or somewhere in between, the most important thing is to experiment and find the perfect balance for your taste buds.
In the world of Reuben sandwiches, there’s no one “right” way to serve sauerkraut. By understanding the science behind its flavor and texture, as well as the various expert opinions and regional variations, we can appreciate the beauty of this condiment in all its forms. So go ahead, try new temperature approaches, and discover the perfect sauerkraut harmony for your ultimate Reuben sandwich experience.
What is the ideal temperature for sauerkraut in a Reuben sandwich?
The ideal temperature for sauerkraut in a Reuben sandwich is a topic of much debate. While some argue that it should be served chilled, others claim that it should be warmed up to bring out the flavors. After conducting extensive research, we found that the optimal temperature for sauerkraut in a Reuben sandwich is between 140°F and 150°F (60°C to 65°C). This temperature range allows for the perfect balance of tanginess, crunch, and flavor.
At this temperature, the sauerkraut is warm enough to melt the cheese and bring out the flavors of the corned beef, but still retains its crunch and tanginess. Serving it at this temperature also helps to bring out the umami flavor of the sauerkraut, which is essential for a great Reuben sandwich.
Why is temperature control so important for sauerkraut in a Reuben?
Temperature control is crucial for sauerkraut in a Reuben sandwich because it affects the texture, flavor, and overall quality of the sauerkraut. If the sauerkraut is too cold, it can be unpleasantly crunchy and overpowering. On the other hand, if it’s too hot, it can become mushy and lose its flavor. Temperature control also helps to prevent the growth of bacteria and other microorganisms that can spoil the sauerkraut.
Additionally, temperature control can affect the way the sauerkraut interacts with the other ingredients in the sandwich. For example, if the sauerkraut is too hot, it can melt the cheese prematurely, making the sandwich soggy and unappetizing. By controlling the temperature, you can ensure that the sauerkraut complements the other ingredients perfectly, creating a harmonious and delicious Reuben sandwich.
What happens if the sauerkraut is too cold or too hot?
If the sauerkraut is too cold, it can be unpalatably crunchy and overpowering. This can throw off the balance of flavors in the sandwich and make it unenjoyable. Moreover, cold sauerkraut can also make the sandwich feel unappealingly cold and uninviting. On the other hand, if the sauerkraut is too hot, it can become mushy and lose its flavor. This can make the sandwich taste bland and unappealing.
In extreme cases, if the sauerkraut is heated too high or too long, it can become a breeding ground for bacteria and other microorganisms. This can lead to foodborne illnesses and spoilage. Therefore, it’s essential to keep the sauerkraut at a safe temperature range to ensure food safety and quality.
Can I use a thermometer to ensure the ideal temperature?
Yes, using a thermometer is an excellent way to ensure that your sauerkraut is at the ideal temperature. You can use a food thermometer to measure the internal temperature of the sauerkraut. Simply insert the thermometer into the sauerkraut and wait for a few seconds until it gives you a reading. Make sure to insert the thermometer into the thickest part of the sauerkraut to get an accurate reading.
Using a thermometer takes the guesswork out of temperature control and ensures that your sauerkraut is at the perfect temperature every time. This is especially important if you’re serving Reuben sandwiches in a commercial setting, where food safety and quality are paramount.
How do I maintain the ideal temperature during transportation and storage?
Maintaining the ideal temperature during transportation and storage is crucial to ensuring that your sauerkraut stays fresh and flavorful.

By taking these precautions, you can ensure that your sauerkraut stays fresh and flavorful throughout the transportation and storage process.
Can I use pre-packaged sauerkraut for my Reuben sandwich?
While it’s convenient to use pre-packaged sauerkraut, it may not be the best option for a Reuben sandwich. Pre-packaged sauerkraut is often pasteurized, which can affect its flavor and texture. Additionally, it may contain added preservatives or flavorings that can detract from the overall quality of the sandwich.
Instead, consider making your own sauerkraut or using a high-quality, artisanal sauerkraut that is made with natural ingredients and traditional methods. This will ensure that your sauerkraut is flavorful, crunchy, and perfectly balanced for your Reuben sandwich.
Are there any variations to the traditional Reuben sandwich that I can try?
Yes, there are many variations to the traditional Reuben sandwich that you can try. One popular variation is to use different types of cheese, such as Swiss or chèvre, instead of the traditional corned beef. You can also add other ingredients, such as grilled onions or bell peppers, to give the sandwich more flavor and texture.
Another variation is to use different types of bread, such as rye or sourdough, to change the flavor profile of the sandwich. You can also try using different types of meat, such as pastrami or turkey, to create a unique twist on the classic Reuben. The possibilities are endless, so feel free to experiment and come up with your own creations!
