Why is peanut butter called butter? The surprising history

4 min read

Over 500 million pounds of peanut butter are consumed in the United States every year, yet it contains no dairy. The reason why peanut butter is called butter is due to its spreadable consistency, which reminded early inventors of dairy butter, despite being a completely different product.

Quick Summary

The term 'peanut butter' stems from its butter-like, spreadable texture, a comparison made by early developers and marketers. The name stuck, distinguishing it from peanut paste and other forms while legally sidestepping dairy regulations in many places by historical precedent, though not everywhere. This convention is also seen with other nut and fruit spreads.

Key Points

  • Texture, not Ingredients: Peanut butter is named 'butter' because of its spreadable, creamy texture, not because it contains any dairy.

  • Early Patent & Marketing: Inventors like Marcellus Gilmore Edson and John Harvey Kellogg likened the consistency to butter as an effective marketing tool in the late 19th century.

  • Avoiding Negative Connotations: The name was preferred over "peanut paste," which sounded less appetizing to consumers.

  • International Differences: Some countries, like the Netherlands, legally prohibit the term for non-dairy products, calling it 'pindakaas' (peanut cheese) instead.

  • Other Non-Dairy 'Butters': The naming convention extends to other dairy-free spreads like almond butter, apple butter, and cocoa butter, all named for their consistency.

  • Enhanced Shelf Life: Modern versions were made possible by the 1920s invention of partial hydrogenation, which stabilized the spread and prevented oil separation.

  • Fundamentally Different: Peanut butter and dairy butter have entirely different compositions, with peanut butter containing more protein and fiber, and no dairy fat.

The Consistency Conundrum: Why Name it Butter?

The primary reason for the "butter" in peanut butter is its smooth, creamy, and spreadable texture. This quality is similar to how dairy butter behaves at room temperature. In the late 19th century, when modern peanut butter was patented, its consistency was a key selling point. Rather than inventing a new term for the milled peanut spread, inventors chose a name that communicated a familiar texture and use case to consumers.

The First Patents and Marketing

The history of peanut butter involves several key figures. In 1884, Canadian chemist Marcellus Gilmore Edson filed a patent for a "peanut candy" product, noting its consistency was "like that of butter, lard, or ointment". A decade later, Dr. John Harvey Kellogg filed his own patent for a nut butter made from boiled peanuts, marketing it as an easily digestible protein source for his patients with dental issues. These early iterations used the comparison to butter as a simple, effective marketing tool to explain the product's function.

The Negative Connotation of "Paste"

While early inventors sometimes referred to their product as "peanut paste," the term was quickly abandoned for commercial marketing. The word "paste" can have negative connotations, bringing to mind things like wallpaper paste or adhesive. "Peanut butter," on the other hand, sounded more appetizing, more luxurious, and more aligned with the creamy, rich taste the product offered. This marketing decision had a lasting impact, cementing "butter" in the product's name and avoiding potential consumer aversion.

The Legal and Global Naming Differences

While the name stuck in the United States, not all countries permit the use of the word "butter" for non-dairy products. This is often due to strict food labeling laws designed to protect dairy interests and prevent consumer confusion.

  • The Netherlands: In the Netherlands, it is illegal to sell the product under the name "peanut butter" because the word "butter" is reserved exclusively for dairy products. There, it is called pindakaas, which translates to "peanut cheese." This naming convention dates back to a Dutch colony in Suriname, where a similar peanut dish existed and was sliced like cheese.
  • Australia: Some states in Australia have also historically had restrictions on the term, with the product being known as "peanut paste" in certain regions.

Other "Butters" Without Dairy

Peanut butter is not alone in using the term "butter" to describe a dairy-free spread. The convention extends to a variety of other foods based on their texture and application.

  • Apple butter
  • Almond butter
  • Cashew butter
  • Body butter (a cosmetic product)
  • Cocoa butter
  • Shea butter

In these cases, the term "butter" serves as a descriptor for consistency and use rather than indicating any dairy content.

Peanut Butter vs. Dairy Butter: A Comparative Table

Feature Peanut Butter (Commercial) Dairy Butter Explanation
Primary Ingredient Roasted and ground peanuts Churned cream or milk fat The core difference lies in their fundamental ingredients and origins.
Composition High protein, fiber, and unsaturated fats Predominantly saturated milk fat and water Peanut butter is a more complex food with a broader range of nutrients.
Dairy Content None Yes, exclusively from milk By definition, butter is a dairy product; peanut butter is a legume-based spread.
Storage Shelf-stable (natural varieties may separate) Requires refrigeration to prevent spoilage The use of stabilizers in commercial peanut butter allows for a longer, more convenient shelf life.
Flavor Profile Nutty, sweet, and savory Creamy, salty, or cultured Flavors are derived from their vastly different source materials.
Culinary Use Spreads, sauces, baking, and cooking Spreads, baking, sauces, and frying While both are spreads, they have distinct applications due to their ingredient bases.

The Evolution of the Beloved Spread

Peanut butter was first introduced to a wider audience at the St. Louis World's Fair in 1904, where it was marketed as a nutritious and tasty novelty. However, early versions had poor shelf stability, with the oil separating from the solids. This problem was solved in the 1920s by chemist Joseph Rosefield, who patented a process using partial hydrogenation, a technique already used for commercial lard and butter. This innovation made it possible for peanut butter to be mass-produced and shipped nationwide without spoiling, leading to the rise of major brands like Peter Pan and Skippy. Later, Jif was introduced using different sweeteners and non-peanut oils in the hydrogenation process. The modern product, largely unchanged in concept, owes its success to a combination of inventive spirit, savvy marketing, and critical scientific advancements. The name, based on its texture and usage rather than its ingredients, was a brilliant choice that helped it become the household staple it is today.

Conclusion: A Name of Texture, Not Ingredients

In the end, the simple reason why peanut butter is called butter has everything to do with perception and marketing. Rather than being defined by its lack of dairy, the product was named for its creamy, spreadable consistency, which was a familiar concept to consumers. The shift from "peanut paste" to "peanut butter" made it more appealing and helped it become the popular pantry staple it is today. While legally debated in some parts of the world, the name is a testament to the power of descriptive marketing and the enduring popularity of this unique legume spread. The next time you make a peanut butter and jelly sandwich, you can appreciate the history and ingenuity behind its simple, yet iconic, name.
