Soak the marrowfat peas overnight.
1.Rinse the dried marrowfat peas in a colander under cold water until the water runs clear.2.Transfer peas to a large bowl and add the baking soda.3.Cover with plenty of cold water so the peas are submerged by at least 3 inches.4.Soak at room temperature for 8 hours, or overnight.TIPDon't skip the baking soda — it softens the hard water and helps the peas cook down into that signature mushy texture. - prep · ~2 min
Drain and rinse the soaked peas.
Drain the soaked peas in a colander and rinse thoroughly under cold running water to remove any trace of baking soda.
- simmer · ~55 min
Simmer the peas until tender.
1.Transfer the rinsed peas to a large saucepan and pour in 750 ml of fresh water.2.Bring to a rolling boil over high heat, skimming off any white foam that rises to the surface.3.Reduce heat to low, cover partially with a lid, and simmer gently for 45-55 minutes until the peas are completely tender and starting to break apart.TIPKeep the heat low enough that the peas tremble rather than thrash — vigorous boiling toughens the skins. - mix · ~2 min
Mash the peas into a rustic purée.
1.Remove the saucepan from the heat. Do not drain — the peas will continue to absorb the remaining liquid as they cool.2.Add the butter and salt to the hot peas.3.Mash directly in the pot with a potato masher until you have a thick, slightly chunky purée with no whole peas remaining.TIPMash while hot — the residual heat helps the butter melt evenly and the starch sets up into a proper mushy, not watery, consistency. - mix · ~1 min
Season and finish with lemon and black pepper.
Stir in the lemon juice and a generous pinch of freshly ground black pepper. Taste and adjust salt if needed.

What to keep in mind.
6 tips from the recipe — small details that make a real difference to the final dish.
- 1Soak the peas for the full 8 hours overnight to ensure they soften completely; a shorter soak leads to gritty peas.
- 2Skim the white foam that rises during boiling to keep the final purée clean and not cloudy.
- 3Don't drain the cooking liquid after simmering — let the peas absorb it as they cool for the perfect thick consistency.
- 4Mash the peas while they are still hot so the butter melts seamlessly and the starch thickens properly.
- 5If you want an ultra-smooth purée, use an immersion blender instead of a potato masher, but pulse gently to avoid gumminess.
- 6Mushy peas firm up as they sit; if reheating leftovers, stir in a splash of water and a knob of butter to bring back the creamy texture.
