If you grew up in the South, the sight of a bushel of purple-stained hulls and the earthy, savory aroma of a simmering pot on the stove is the definition of summer. Purple hull peas are more than just a side dish; they are a cultural staple, a labor of love, and a nutritional powerhouse. Whether you’ve just come home from a local farmer’s market with a fresh haul or you’ve found a bag of frozen peas in the grocery store, knowing how to cook them correctly is the difference between a bland bowl of legumes and a soulful, flavorful masterpiece.
Understanding the Purple Hull Pea
Before we dive into the pot, it’s helpful to understand what makes these peas special. Purple hull peas are a subspecies of the cowpea, closely related to the black-eyed pea. However, true aficionados will tell you that the purple hull is superior. They have a creamier texture and a slightly sweeter, milder flavor than their black-eyed cousins.
The name comes from the vibrant, deep purple color of the pods when they reach maturity. When you shell them, the peas inside are usually creamy white with a tiny pink or purple “eye.” They are traditionally harvested in the heat of mid-to-late summer, making them a centerpiece of Southern garden-to-table cooking.
Fresh vs. Frozen vs. Dried
The method you choose for how to cook purple hull peas will depend largely on the state of the peas you are starting with.
Fresh Peas
Fresh peas are the gold standard. If you buy them in the hull, you’ll need to spend some time “shelling” them. This is often a social activity in the South, done on a porch with a cold drink. Once shelled, they require a good rinse to remove any grit or bits of hull. Fresh peas cook relatively quickly, usually in about 45 to 60 minutes.
Frozen Peas
High-quality frozen purple hull peas are an excellent alternative when they aren’t in season. Most frozen peas are blanched before freezing, which helps preserve their color and texture. You can cook these directly from frozen, and they typically take about the same amount of time as fresh peas.
Dried Peas
Dried purple hull peas are less common than dried black-eyed peas but can be found in specialty shops. These require a soaking period (either overnight or a quick-soak method) and a much longer simmer time, often 1.5 to 2 hours, to reach the desired tenderness.
The Secret is in the Pot Liquor
In Southern cooking, the liquid left behind after boiling greens or beans is known as “pot liquor” (or potlikker). This liquid is liquid gold. It is a concentrated broth of pea starch, salt, and fat from the seasoning meat. When you learn how to cook purple hull peas, your goal isn’t just to soften the peas; it’s to create a rich, savory gravy that coats every bite. This is why you never drain your peas after cooking. You serve them in their juice, ideally with a hunk of cornbread to soak it all up.
Selecting Your Seasoning Meat
The foundation of a great pot of peas is the meat used for seasoning. While you can certainly make vegetarian peas, the traditional Southern method relies on pork for depth and saltiness.
Smoked Ham Hocks
Ham hocks are perhaps the most traditional choice. They provide a deep, smoky flavor and release collagen as they simmer, which gives the pot liquor a silky, rich mouthfeel.
Salt Pork or Fatback
If you want a cleaner, saltier flavor without the heavy smoke, salt pork or fatback is the way to go. This is essentially cured pork fat with very little meat. It renders down into the peas, providing a luxurious richness.
Smoked Turkey Wings or Necks
For those who prefer to avoid pork, smoked turkey is a fantastic substitute. It provides that essential smokiness and plenty of savory protein without the heavy grease of pork fat.
Bacon
In a pinch, thick-cut smoked bacon works well. Sautéing the bacon in the pot before adding the water and peas allows you to build layers of flavor starting with the rendered fat.
Step-by-Step Guide to Cooking Purple Hull Peas
Now that we understand the ingredients, let’s walk through the process of creating a classic pot of Southern purple hull peas.
Preparation and Cleaning
If using fresh peas, shell them and place the peas in a large bowl of cool water. Swish them around to let any dirt or debris sink to the bottom. Any “floaters” (peas that rise to the top) are usually hollow or bug-eaten and should be discarded. Drain and rinse them one more time.
Building the Flavor Base
Start by placing your seasoning meat of choice into a large heavy-bottomed pot or a Dutch oven. Add about 6 to 8 cups of water (enough to cover the peas by at least 2 inches later). Bring this to a boil, then reduce the heat and simmer the meat for about 30 minutes. This “pre-boil” ensures the meat is tender and the water is already flavored before the peas even hit the pot.
Adding the Peas and Aromatics
Once your broth is started, add the cleaned peas to the pot. At this stage, you can also add aromatics. A small yellow onion, finely diced, and a clove or two of smashed garlic are classic additions. Some cooks also like to add a pinch of sugar to highlight the natural sweetness of the peas.
The Simmer
Bring the pot back up to a gentle boil, then immediately turn the heat down to low. You want a lazy simmer, not a rolling boil. If you boil them too hard, the skins will pop off and the peas will turn to mush. Cover the pot with a lid, leaving it slightly ajar to allow a small amount of steam to escape.
Timing and Tenderness
Fresh or frozen purple hull peas usually take between 45 minutes and an hour. Start checking them at the 40-minute mark. You are looking for a “tender-but-firm” consistency. They should be soft enough to mash against the roof of your mouth but still hold their shape.
Final Seasoning
Wait until the peas are almost finished cooking before adding extra salt. Since seasoning meats like ham hocks and salt pork are very salty, adding salt too early can result in an oversalted dish. Taste the broth near the end and add salt and a generous amount of freshly cracked black pepper.
Essential Tips for Success
- Do not over-stir the peas. Constant stirring can break the delicate skins and make the pot look messy. A gentle stir every 15 minutes is plenty.
- If you find that your pot liquor is too thin, you can take a spoonful of peas out, mash them into a paste, and stir them back into the pot. The starch will act as a natural thickener.
- Always serve your peas with a “bright” condiment. In the South, this usually means a splash of apple cider vinegar, a spoonful of hot sauce, or “pepper vinegar” (small hot peppers steeped in vinegar). The acidity cuts through the richness of the pork and the earthiness of the peas.
Serving Suggestions
Purple hull peas are versatile. While they are a meal on their own when served with cornbread, they are traditionally part of a larger Southern spread. They pair beautifully with fried okra, sliced garden tomatoes, creamed corn, and mashed potatoes. For a complete “meat and three” meal, serve them alongside fried chicken or a pork chop.
Storing and Reheating
Like many stews and beans, purple hull peas often taste better the next day. The flavors have more time to meld, and the pot liquor thickens even further in the refrigerator. They will stay fresh in an airtight container for up to 5 days. When reheating, do so gently on the stovetop over low heat, adding a splash of water or chicken broth if the liquid has become too thick.
FAQs
Can I cook purple hull peas in a slow cooker?
Yes, purple hull peas work very well in a slow cooker. You can place the peas, seasoning meat, aromatics, and water in the crock and cook on low for 6 to 8 hours or on high for 3 to 4 hours. This is a great “set it and forget it” method for busy days.
Why did my purple hull peas turn the water dark?
It is completely normal for the cooking liquid to turn a dark, brownish-purple hue. This comes from the pigments in the “eye” of the pea and the skins themselves. This dark liquid is the highly prized pot liquor and is full of flavor.
Do I need to soak fresh purple hull peas?
No, fresh purple hull peas do not require soaking. Only dried peas need to be soaked to rehydrate them. Fresh peas have a high moisture content and will cook to tenderness relatively quickly without any pre-soaking.
Is it possible to cook purple hull peas without meat?
Absolutely. To achieve a similar depth of flavor without pork, use vegetable broth instead of water and add a teaspoon of liquid smoke or smoked paprika. Sautéing onions, celery, and bell pepper (the “holy trinity“) in olive oil before adding the peas also helps build a savory base.
Can I freeze cooked purple hull peas?
Yes, cooked purple hull peas freeze beautifully. Allow them to cool completely, then ladle the peas and their liquid into freezer-safe bags or containers. They will last for up to 6 months. Thaw them overnight in the refrigerator before reheating.
