Why Southerners Call Lima Beans 'Butter Beans'
At its core, the reason southerners call lima beans butter beans is a matter of both geography and texture. The name 'lima bean' is derived from Lima, Peru, where the legume was first cultivated. However, as the beans were introduced to different regions, their name evolved to reflect local characteristics and preparations. For the Southern palate, the beans' smooth, rich, and creamy consistency when cooked evokes the rich flavor of butter, leading to the name 'butter bean'. This buttery taste and velvety mouthfeel are particularly prominent in the larger, mature varieties, which often have a pale, beige color.
The Role of Geography in Naming
While the lima bean's origin lies in Peru, its spread across the globe led to the development of many regional names. In the United States, the North tends to stick with the original 'lima' designation, while the South overwhelmingly prefers 'butter bean'. This distinction is so prevalent that a bag of dried beans in a Southern grocery store might be labeled 'lima beans' on the packaging but will almost certainly be called butter beans in conversation among locals. The term 'butter bean' is also used in the United Kingdom, further showcasing the global nature of this linguistic drift.
Culinary Tradition and Preparation
The Southern tradition of cooking legumes, often involving simmering them with smoked pork like ham hocks or bacon, further reinforces the association with richness and creaminess. This cooking method enhances the natural flavors and buttery texture of the beans. The regional name is not just a random quirk but a cultural reference deeply tied to how the beans are prepared and enjoyed. For many Southerners, a pot of slow-simmered butter beans is the epitome of comfort food.
Butter Beans vs. Lima Beans: Common Misconceptions
Many people outside the South mistakenly believe that butter beans and lima beans are two different types of legumes. This is a common and understandable point of confusion. Here’s a breakdown of the differences, real and perceived:
- 
The Same Species: The most important thing to know is that they are the same species: Phaseolus lunatus. Any perceived differences in taste or texture are typically due to the bean's maturity or preparation method, not a fundamental biological difference. 
- 
Maturity Levels: Younger, fresh, and often green beans are sometimes specifically called 'baby limas,' while the older, mature, beige-colored beans are what most Southerners refer to as butter beans. Some people make a culinary distinction, with green baby limas being milder and the mature, larger butter beans having a sweeter, more buttery flavor. 
- 
The Power of Branding: The food industry has sometimes contributed to the confusion by labeling packages of dried or canned beans differently. It's not uncommon to see the exact same beans marketed as 'Lima Beans' in one region and 'Butter Beans' in another. 
Varieties within the Lima/Butter Bean Family
Just to make things more interesting, there are also different varieties of lima beans that can go by either name, depending on where you are. Some common types include:
- Sieva Beans: A small-seeded type often found in the American South, traditionally called butter beans.
- Dixie Butterpea: A popular small-seeded bush variety grown in the South.
- Fordhook: A popular midseason, large-seeded bush variety.
- Christmas/Speckled Calico: A large, speckled variety, also referred to by some Southerners as a type of butter bean.
The History and Culinary Traditions of Southern Butter Beans
The integration of the lima bean into Southern cuisine is a story with deep roots, influenced heavily by Native American foodways. Indigenous peoples grew a combination of corn, beans, and squash—the 'three sisters'—and beans provided essential nitrogen to the soil. This tradition was passed down, and legumes, including the lima bean, became a cornerstone of Southern cooking. Dishes like succotash, a savory mix of corn and beans, have Native American origins. Over generations, Southern cooks developed unique ways to prepare these beans, which further solidified the 'butter bean' moniker. The addition of smoky, savory pork products is a distinctly Southern touch, infusing the beans with deep flavor.
How to Cook Perfect Butter Beans
Cooking delicious, creamy butter beans is a straightforward process, but it requires patience to achieve the classic Southern texture. For dried beans, soaking them overnight is often recommended, though not strictly necessary. A quick-soak method (boiling and then resting) also works well. The key is to simmer the beans low and slow with a flavorful base, which typically includes water or broth, and a piece of smoked pork. The longer they simmer, the creamier and richer they become. Adding aromatics like onion, garlic, and herbs elevates the flavor profile, creating a comforting and hearty dish.
Comparison of Preparation Methods
| Method | Best For | Typical Flavor Profile | Advantages | Disadvantages | 
|---|---|---|---|---|
| Dried Beans (Soaked) | Traditional Southern comfort food | Rich, creamy, deeply flavored from ham hock | Best texture, rich flavor | Longer preparation and cooking time | 
| Dried Beans (Quick-Soak) | When you have less time to prepare | Slightly less developed flavor than overnight soak | Faster than full soak | Slightly less intense flavor, higher chance of splitting | 
| Canned Beans | Quick meals, salads, side dishes | Milder flavor, less complex | Fast, convenient | Softer texture, less robust flavor from canned liquid | 
| Fresh Beans | Optimal for summer cooking and milder flavor | Tender, slightly sweeter, delicate flavor | Best for salads or light side dishes | Less available year-round, shorter shelf life | 
Conclusion
While the official name might be the lima bean, the endearing and culturally significant name 'butter bean' is what truly captures the essence of this legume in the American South. From family recipes passed down through generations to regional dialects, the term reflects a rich history of culinary tradition, agricultural heritage, and a deep appreciation for good food.
