Maris Piper Potatoes

The Maris Piper earned its reputation for a reason. Cut one open after thirty minutes in a hot oven and you get that clean fluffy interior home cooks dream about. Parboil, rough up the edges, roast in hot fat, and you are looking at the best roast potato you have made this year.

Floury enough for proper mash. Starchy enough for chips that crisp up without a fight. There is a reason every fish and chip shop worth knowing about runs Maris Piper.

If you are new to cooking potatoes seriously, start here. The Maris Piper teaches you what a good roast potato is supposed to taste like.

Maris Piper is the most widely grown potato variety in the United Kingdom, it has been since 1980. The name comes from Maris Lane in Cambridge, where the Plant Breeding Institute developed it in the 1960s. The "Piper" was suggested by the breeder's son, who thought potato varieties should start with "P." 

What emerged from that Cambridge program was a variety with unusually high dry matter and low reducing sugars, the precise combination that gives you a light, fluffy interior and a genuinely crispy exterior when roasted or fried. Every British chip shop knows it. Every serious home cook eventually finds their way to it.

In Australia, that's the catch. Maris Piper is not commonly commercially stocked by supermarkets here. For decades, British expats and food curious home cooks have gone looking for it and come up short. 

Spud Sisters are one of the very few suppliers in the country who does, which is why this page is where people end up when they search for it!

The flavour is exactly what the reputation promises: clean, full, and unmistakably potato. Roasted at high heat with good oil, the exterior shatters. The inside is dry and fluffy, not dense or waxy. For mash, it produces the light, cloud like result that creamy varieties can't quite replicate. And for chips, proper chips, there's nothing better grown in Australian soil.

Spud Sisters sources from the best growers in Victoria's Central Highlands, the same region where the family's farming history is rooted, along with the Southern Highlands. 

Farms raise Maris Piper from certified seed using natural methods of disease and pest control.

This is where Maris Piper earns its reputation. Parboil cut potatoes in salted water for 10–12 minutes first. Add a small pinch of bicarb soda to the boiling water, this roughens the surface of the potato and creates more surface area for the oil to grip, which is what gives you that proper crust. Drain well and let them steam-dry in the pot for a full minute before doing anything else.

Preheat your roasting tray in the oven at 200–210°C, and heat a generous layer of oil in it at the same time, you want both hot before the potatoes go in. Toss your parboiled potatoes in oil, season well, then carefully place them in the hot tray. You should hear them sizzle. Roast for around an hour, turning once halfway through. Do not rush them.

The result: a potato that shatters when you cut it, fluffy and dry inside.

Maris Piper is the chip potato. Slice into thick chips or wedges, toss in oil and seasoning, and roast at 210°C for 35–45 minutes. For thinner, crispier chips, parboil for 5 minutes first. For an air fryer, Maris Piper and Russet are the best starchy varieties, parboil briefly, then air fry at 200°C for 20–25 minutes.

Boil gently, not at a rolling boil, which breaks down the exterior before the centre is cooked through. Drain, steam dry in the pot, then mash. Maris Piper produces a light, fluffy mash rather than the dense, creamy result you get from Dutch Cream. For the creamiest possible result, use Dutch Cream. For the lightest and most voluminous mash, Maris Piper is the better choice.

Pierce the skin, rub with oil and salt, and bake at 200°C for 60–75 minutes depending on size. The high dry matter content of Maris Piper produces a properly fluffy baked interior, the kind that falls apart when you fork it open.

For a blended or creamy potato soup, Maris Piper breaks down beautifully and produces a naturally thick, smooth result without needing cream to compensate.

• Peel for roasting and mashing; skin on works well for wedges and smashed potatoes.
• The bicarb soda tip (quarter teaspoon per small pot, half per medium) is the single biggest upgrade to a roast potato, don't skip it.
• If any green tinge appears on the skin, cut it away generously. Standard advice for all varieties, light exposure, not a quality issue.
