Chip shop mushy peas are a British classic, traditionally served alongside fish and chips. This version uses dried marrowfat peas, which break down into a thick, creamy, and slightly sweet puree with a distinctive earthy flavor. Unlike the bright green canned versions, authentic mushy peas have a muted, sage-green color and a comforting, starchy texture that pairs perfectly with crispy fried foods.
Ingredients
- 2 cups (400 g) dried marrowfat peas (or dried green split peas as a substitute)
- 1 tsp (5 g) baking soda (bicarbonate of soda)
- 1 tbsp (15 g) sugar
- 1 tsp (5 g) salt, plus more to taste
- 4 cups (1 L) water, for soaking
- 2 cups (500 ml) water, for cooking
- 2 tbsp (30 g) butter or margarine (optional, for richness)
- Freshly ground black pepper, to taste
Instructions
- Soak the peas: Place the dried marrowfat peas in a large bowl and cover with the 4 cups (1 L) of water. Stir in the baking soda. The baking soda helps soften the pea skins and speeds up the soaking process. Cover and leave at room temperature for at least 8 hours or overnight. The peas will swell significantly, so use a large bowl.
- Drain and rinse: After soaking, drain the peas in a colander and rinse them thoroughly under cold running water. This removes the baking soda, which can leave a bitter taste if not washed off.
- Cook the peas: Transfer the soaked peas to a large saucepan or Dutch oven. Add the 2 cups (500 ml) of fresh water and bring to a boil over high heat. Reduce the heat to low, cover, and simmer gently for 45 minutes to 1 hour, or until the peas are very soft and starting to break apart. Stir occasionally to prevent sticking.
- Season and mash: Once the peas are tender, add the sugar, salt, and butter (if using). Use a potato masher or a wooden spoon to mash the peas to your desired consistency. Traditional mushy peas are thick and slightly chunky, not completely smooth. If they seem too dry, add a splash of water or milk to loosen them. Taste and adjust seasoning with more salt and pepper as needed.
- Simmer to thicken: Return the mashed peas to low heat and simmer uncovered for 10–15 minutes, stirring frequently, until they reach a thick, porridge-like consistency. They should hold their shape on a spoon but still be soft and creamy.
- Serve: Serve hot, spooned alongside fish and chips, or as a side to any British-style meal.
Tips
- Soaking is essential: Do not skip the overnight soak. Marrowfat peas are very hard and need the long soak to soften properly. If you’re short on time, you can use the “quick soak� method: boil the peas with the baking soda for 2 minutes, then let them sit in the hot water for 1 hour before draining and cooking.
- Substitute for marrowfat peas: If you can’t find marrowfat peas (often sold in British or Irish specialty stores), use dried green split peas. They will produce a slightly smoother puree, but the flavor will be very close. You may need to reduce the cooking time by about 15 minutes.
- Don’t over-mash: The best texture is slightly lumpy, not a smooth puree. Over-mashing can make them gluey. Use a potato masher and stop when you still have a few small pea pieces.
- Balance the sweetness: The sugar is traditional and balances the natural bitterness of the peas. Start with 1 tablespoon and add more only if needed. Some people prefer a more savory version with just salt and pepper.
Serving Suggestions
Serve mushy peas as a classic side to fish and chips, or alongside battered sausages, pies, or a traditional British roast dinner. They also pair well with grilled meats or as a topping for toast. A sprinkle of malt vinegar and a pinch of salt over the peas is the authentic finishing touch.
Variations
- Minty mushy peas: Stir in 2 tablespoons of chopped fresh mint during the last 5 minutes of cooking for a fresh, bright flavor.
- Spicy version: Add a pinch of cayenne pepper or a finely chopped fresh chili along with the salt for a subtle heat.
- Vegan option: Omit the butter and use olive oil or a vegan butter substitute. The peas are naturally vegan, so this is an easy swap.
- Pea and ham: For a heartier side, add 1 cup (150 g) of diced cooked ham during the last 10 minutes of cooking.
Storage and Reheating
Mushy peas will keep in an airtight container in the refrigerator for up to 4 days. They also freeze well for up to 3 months. To reheat, place them in a saucepan with a splash of water or milk and warm over low heat, stirring frequently, until heated through. You can also reheat in the microwave in 30-second bursts, stirring in between. If the peas have thickened too much after refrigeration, add a little water to loosen them to the desired consistency.
Frequently Asked Questions
Can I use canned mushy peas instead of dried? Yes, canned mushy peas are a convenient shortcut. Simply heat them in a saucepan over medium heat for 5–7 minutes, stirring occasionally. However, they are often more watery and less flavorful than homemade, so you may want to simmer them longer to thicken and add extra salt and pepper.
What are marrowfat peas? Marrowfat peas are a variety of large, starchy green peas that are harvested mature and dried. They are the traditional pea used for mushy peas in the UK. They have a higher starch content than regular green peas, which gives them their characteristic creamy texture when cooked.
Why do I need baking soda? Baking soda (bicarbonate of soda) helps soften the pea skins during soaking, allowing the peas to absorb water more quickly and cook more evenly. It also helps maintain a slightly green color. It’s important to rinse the peas thoroughly after soaking to remove any residual baking soda, which can make them taste bitter.
Can I make mushy peas without soaking? You can, but the cooking time will be significantly longer—often 2 to 3 hours. The peas may also remain slightly chewy if the skins don’t soften properly. The overnight soak is highly recommended for the best texture and flavor.
Are mushy peas healthy? Mushy peas are low in fat and a good source of fiber and plant-based protein. They are naturally cholesterol-free. The main additions are sugar and salt, so you can control the amount to suit your dietary needs.
Can I use frozen peas? Frozen peas are not suitable for making traditional mushy peas because they are too sweet and have a much higher moisture content. They will produce a watery, sweet puree rather than the starchy, savory texture of authentic mushy peas. Stick with dried peas for the real thing.
