This Classic Pepper Sandwich Filling is a delicious relic from a time when “mango” didn’t refer to the tropical fruit, but instead to peppers. This unique and flavorful recipe was common in certain parts of the Midwest and Southern United States during the 18th and 19th centuries. With a tangy, sweet, and slightly spicy flavor profile, this pepper-based sandwich filling is made by combining ground peppers, sugar, vinegar, and mustard, cooked together for 20 minutes. The end result is a tasty spread that can be used on sandwiches, crackers, or alongside meats and cheeses. The recipe also calls for sealing the filling with paraffin, a traditional preservation method, which can be substituted with modern canning techniques today.

Sandwich Filling
Food History
The use of the term “mango” to describe peppers has an interesting origin in American culinary history. In the 1700s, when pickling and preserving were essential for extending the life of fruits and vegetables, the word “mango” was borrowed from the Indian practice of pickling the tropical mango fruit. Over time, in parts of the U.S.—especially in states like Ohio, Illinois, and Indiana—the term started being applied to any pickled fruit or vegetable, including bell peppers.
Bell peppers, often stuffed or pickled, became a staple of American households, and the term “mango” stuck for several generations. By the 20th century, this practice largely disappeared as the term mango returned to its original meaning: the tropical fruit. However, recipes like this one are a fascinating glimpse into the rich and sometimes quirky history of American food traditions.
This recipe reflects not just the unique terminology of the time, but also the practice of food preservation before modern refrigeration. In the days before refrigerators, families used methods like pickling and paraffin sealing to keep their food edible for longer periods. Paraffin, a wax, would be poured over the top of the jars to create an airtight seal, protecting the contents from spoilage.

Recipe Discussion
This Classic Pepper Sandwich Filling recipe is both simple and flavorful. It starts with grinding 18 peppers, which would likely have been bell peppers or a similar type. The peppers are then boiled together with sugar, vinegar, salt, butter, flour, and dry mustard. The combination of these ingredients creates a sweet, tangy, and slightly savory spread that works well as a filling for sandwiches or as a topping for crackers.
The vinegar and sugar work together to balance the sharpness of the peppers, while the flour helps thicken the mixture into a more spreadable consistency. The butter adds a bit of richness to the flavor, and the mustard introduces a subtle spicy note that complements the peppers’ natural sweetness.
One key point to note is that the recipe originally instructs you to seal the jars with paraffin wax. This was a common method used in the early to mid-20th century to preserve foods. Paraffin, however, has fallen out of favor due to concerns about its effectiveness in creating a lasting seal. Cracks can form in the wax, which can let in air and spoil the food.
Today, modern canning methods, such as water bath canning, are much safer and more effective. Instead of using paraffin, you can fill sterilized jars with the hot mixture, leaving about a half-inch of space at the top, and process the jars in boiling water for about 10 minutes. This will create a vacuum seal, ensuring the filling stays fresh for much longer.
Preparation Tips
Here are some tips to help ensure your pepper sandwich filling turns out perfectly:
- Use fresh peppers: For the best flavor, use fresh, firm peppers. Green bell peppers work well for a more savory flavor, but you can mix in red, yellow, or orange peppers for a bit of sweetness.
- Grind evenly: If you don’t have a food processor, use a hand grinder or finely chop the peppers. This ensures the spread has a smooth, even texture.
- Choose the right vinegar: White vinegar is standard in this recipe, but apple cider vinegar can add a slightly more complex, fruity flavor.
- Thicken properly: The flour helps thicken the mixture as it boils, but if you’re gluten-free, you can substitute cornstarch. Just dissolve it in water before adding to prevent lumps.
- Sterilize your jars: Before filling your jars and lids, boil them in water for at least 10 minutes. This helps prevent spoilage and extends the shelf life of your filling.
- Modern canning method: Instead of paraffin, opt for water bath canning for a more reliable seal and longer preservation time.

Why is peppers added in parentheses after mangoes in the ingredients? Is it mangoes or peppers?
