Proper Mushy Peas

This is the real chip-shop side: marrowfat peas cooked down until they collapse into a thick, spoon-coating green sludge, seasoned hard with salt, sugar and malt vinegar. A pinch of bicarbonate of soda breaks the skins so the peas go properly creamy instead of grainy. Ready in about 35 minutes on the hob, no overnight soak required.

Every chip shop has a vat of mushy peas on the go, and the good ones are nothing like the sad tinned stuff. Real mushy peas are thick enough to hold a spoon upright, glossy rather than watery, savoury-sweet, and sharpened at the last second with malt vinegar. Get the texture right and they stop being a side order and start being the best bit of the plate.

Ingredients

• 2 x 300g tins marrowfat processed peas — drained; Batchelors Bigga or Farrow's Giant are the chip-shop standard
• 200ml cold water
• 1/4 tsp bicarbonate of soda — the texture trick - don't skip, and don't overdo it
• 25g salted butter — or a good plant butter to keep it dairy-free
• 1 tsp caster sugar
• 1/2 tsp fine salt — plus more to taste - these need proper seasoning
• 1/4 tsp ground white pepper
• 2 tsp malt vinegar — added off the heat, at the end
• 1 tbsp chopped fresh mint — optional, for a fresher pub-style version

Method

1. Drain the peas in a sieve and give them a quick rinse under cold water to wash off the thick tinning liquor, which tastes flat and metallic. Shake them dry.
2. Tip the peas into a medium heavy-based saucepan with the 200ml water and the bicarbonate of soda. Stir once and set over a medium heat.
3. Bring to a gentle simmer, then turn the heat down low. Cook uncovered for 15 minutes, stirring every couple of minutes and scraping the base of the pan so nothing catches. The peas will start losing their edges and the liquid will turn cloudy and green.
4. Once they are visibly softening, mash firmly against the side of the pan with a potato masher or the back of a wooden spoon. Go for about three quarters mashed - you want a thick puree with some whole peas left in for texture, not baby food.
5. Add the butter, sugar, salt and white pepper. Keep cooking on a low heat for another 8-10 minutes, stirring often, until the mixture is thick enough that a spoon dragged through the pan leaves a channel that holds for a second before closing.
6. Check the consistency. Too stiff, loosen with a splash of hot water; too loose, keep it bubbling and stirring for a few more minutes - it will always tighten a little as it cools.
7. Take the pan off the heat and stir in the malt vinegar, plus the mint if using. Taste and adjust: these want noticeably more salt than you think, and enough vinegar that they taste bright rather than sour.
8. Serve hot, piled up in a bowl or straight alongside chips, with an extra shake of vinegar and a grind of pepper on top.

Serve it with

• Battered fish and thick-cut chips
• Steak and ale pie or a proper meat-free mushroom pie
• Chip butties, with the peas spooned straight in
• Fishcakes or breaded halloumi with tartare sauce
• Bangers and mash with onion gravy

Why this works

The alkaline pinch of bicarbonate of soda softens the pectin in the marrowfat pea skins so they break down completely instead of staying grainy - that is what gives chip-shop peas their smooth, glossy body. Finishing with butter for richness and malt vinegar off the heat keeps the sharpness bright, because vinegar added while boiling just cooks away.

Common swaps

• Dried marrowfat peas: soak 250g overnight in cold water with a bicarb tablet or 1/2 tsp bicarbonate of soda, drain, then simmer in fresh water for 45-60 minutes before mashing and seasoning as above.
• No marrowfat peas? Frozen garden peas make a sweeter, brighter 'pub-style' version - simmer 5 minutes, drain, then mash with the butter and seasoning. Skip the bicarb.
• Swap butter for olive oil or plant butter to make them vegan.
• Cider vinegar or a squeeze of lemon in place of malt vinegar for a cleaner, less chip-shop finish.
• Stir in a teaspoon of vegetable bouillon powder with the seasoning if you want a deeper, savoury pub-kitchen flavour.

Common mistakes to avoid

• Adding too much bicarbonate of soda. More than a quarter teaspoon here turns the peas soapy and slippery, and dulls the colour to army green.
• Not cooking them down far enough. Watery mushy peas run all over the plate - keep the pan uncovered and let the liquid reduce until the mixture holds a channel.
• Under-seasoning. Marrowfat peas are bland on their own and need real salt, a little sugar and white pepper to taste like the takeaway version.
• Adding the vinegar early. Boil it and the sharpness disappears - it goes in off the heat, right at the end.

Storage, freezing & reheating

Storage: Cool quickly, then keep covered in the fridge for up to 3 days. They will set firm when cold, which is normal.

Freezing: Freezes well for up to 3 months. Freeze in portions in sealed tubs and defrost overnight in the fridge before reheating.

Reheating: Reheat in a saucepan over a low heat with a splash of water, stirring until loose and steaming hot throughout. Add a fresh few drops of malt vinegar just before serving to wake the flavour back up - microwaving works but stir halfway or the edges will catch and go pasty.
