Prep: 8 hrs 10 mins (includes soaking) Cook: 35–50 mins (dried) / 10 mins (frozen) Total: 8 hrs 45 mins (dried) / 20 mins (frozen) Yield: 4 servings Cuisine: British Category: Side Dish

Ingredients

  • 250g (about 1 cup) dried marrowfat peas, rinsed (or 450g frozen garden peas for quick method)
  • 1/2 teaspoon baking soda (if using dried peas)
  • 1 teaspoon fine salt, plus more to taste
  • 2–3 tbsp unsalted butter or extra-virgin olive oil (use vegan butter or oil to keep vegan)
  • Freshly ground black pepper, to taste
  • 1–2 tbsp chopped fresh mint (optional but traditional)
  • Water or vegetable stock for cooking

Equipment

  • Large bowl for soaking
  • Large saucepan with lid
  • Sieve or colander
  • Potato masher or immersion blender
  • Wooden spoon or spatula

Instructions

  1. Soak (dried peas): Place dried marrowfat peas in a large bowl and cover with cold water by 5cm (2 inches). Stir in 1/2 tsp baking soda, cover and leave to soak overnight (8–12 hours). The baking soda helps soften the skins and intensify the green color.
  2. Rinse: Drain and rinse the peas thoroughly under cold running water to remove excess baking soda.
  3. Simmer gently: Put the drained peas in a saucepan and cover with fresh water or stock by about 2cm (1 inch). Bring to a gentle simmer, skim any foam, cover partially and cook very gently for 35–50 minutes until the peas collapse and are very soft. Add a pinch of salt in the final 10 minutes. Keep the heat low to avoid graininess.
  4. Drain and mash: Drain most of the cooking liquid, reserving a little. Mash the peas with a potato masher to your preferred texture — leave some whole peas for a chunky mush or mash until smooth. Return to the pan.
  5. Finish: Stir in butter or olive oil, seasoning with salt and freshly ground black pepper. Add chopped mint if using. If the mixture is too thick, loosen with a splash of the reserved cooking liquid or hot water until creamy.
  6. Quick method (frozen peas): For a speedy version, simmer 450g frozen garden peas in a little water or stock for 5–8 minutes until very tender. Drain, mash, and finish as above. Add a pinch of baking soda (a light 1/8 tsp) if you want to encourage a brighter green — but use sparingly with frozen peas.
  7. Serve: Keep warm and serve immediately alongside fish and chips, meat pies, or sausages, or spoon over toast.

Pro tips: To achieve a bright green color, add a pinch of baking soda while soaking and cook gently; avoid boiling vigorously. Mash gently and finish on low heat to prevent graininess. For a silky purée, blend briefly with an immersion blender and add extra butter or oil.

Serving ideas

  • Classic: with fish and chips and a wedge of lemon.
  • As a side for meat pies, bangers (sausages) or roast pork.
  • Spread on thick toast with a drizzle of olive oil and cracked pepper.
  • Use as a base pea purée for grilled fish or seared scallops.

FAQ

Q: Can I use frozen peas instead of dried marrowfat peas?

A: Yes. Frozen garden peas are the quickest option and still tasty; they give a fresher, slightly sweeter result but a different texture. For the authentic silky mush associated with British mushy peas, dried marrowfat peas are preferred.

Q: Why add baking soda?

A: A small amount of baking soda raises the pH and softens the pea skins, helping them break down and encouraging a brighter green color. Use sparingly — too much can give a soapy taste.

Q: How long should I soak dried peas?

A: Soak marrowfat peas for 8–12 hours or overnight. Shorter soaks may increase cooking time. You can also do a quick soak: cover with boiling water and leave for 1 hour, then drain and cook longer.

Q: Troubleshooting — my mushy peas are too runny or too starchy. What now?

A: If too runny, simmer uncovered to reduce and thicken or stir in more mashed peas. If starchy or grainy, you may have boiled too hard; try blending briefly for a smoother texture and finish with butter or oil to enrich.

Make-ahead & storage: Cool completely, transfer to an airtight container and refrigerate up to 4 days or freeze up to 3 months. Reheat gently on the stovetop with a splash of water or stock, stirring to restore creaminess.
