Detailed method
Total progress: 0 % done
Phase 1: Preparing the potatoes – 10 minutes
Appliances: Peeler, knife, large pan
1. Peel the potatoes and cut them into even chunks of about 4 cm. This ensures they cook at the same rate. Place them in a large pan and cover with cold water by about 2 cm. Add the fine sea salt.
Check: The potato chunks are even, the water is clear and covers them by about 2 cm.
Before you continue:
Always start with cold salted water, not hot. Starting with hot water cooks the outside faster than the inside and gives you lumpy mash.
Phase 2: Boiling – 15–20 minutes
Appliances: Large pan, hob
2. Bring to the boil, then reduce the heat to a gentle simmer. Cook for 15–20 minutes, until a sharp knife slides into the largest chunk without resistance.
Check: A knife slides in easily and the potato crumbles slightly when lifted. If it falls apart completely, it is overcooked.
Before you continue:
Do not overcook the potatoes. Overcooked potatoes absorb too much water and the mash becomes gluey instead of fluffy.
Phase 3: Drying and mashing – 5 minutes
Appliances: Colander, masher or potato ricer
3. Drain the potatoes in a colander and leave them to steam-dry for 2 minutes. Return them to the warm pan and mash them thoroughly, or pass them through a potato ricer for a lump-free texture.
Check: The mash is smooth and lump-free. If using a ricer, the texture is like fine couscous at this stage.
Before you continue:
Never use a food processor or a blender for mash. The blades break down the potato starch and the mash turns into a sticky, gluey paste.
Phase 4: Enriching – 3 minutes
Appliances: Small pan, wooden spoon
4. Warm the milk in a small pan over low heat – do not let it boil. Add the cubed butter to the mash, then pour in the warm milk a little at a time, stirring gently with a wooden spoon until fully absorbed. Season with salt, white pepper and a pinch of nutmeg.
Check: The mash is silky, glossy and holds a soft peak when lifted with a spoon. It should not be runny.
Before you continue:
Never add cold milk to hot potatoes. The mash will seize up and become gluey. Always warm the milk first.
Phase 5: Serving – 2 minutes
Appliances: Serving bowl
5. Transfer the mash to a warm serving bowl and serve immediately. If you need to hold it for a few minutes, cover with a lid and place over a pan of simmering water.
Check: The mash is warm, silky and glossy, with a rich buttery aroma.
Equipment needed
| Utensil | Ideal size | Alternative | Risk |
|---|---|---|---|
| Large pan with lid | 4–5 l | Large saucepan | Small pan – the potatoes will not fit in a single layer |
| Potato ricer or masher | Standard | Fork | A fork takes longer and leaves lumps |
| Small pan for milk | 0.5 l | Microwave-safe jug | Cold milk will make the mash gluey |

WAGUU Professional level
- Professional standard: Verified recipe with exact ratios and visual checkpoints.
- Tip 1: Always use floury potatoes for mash – Maris Piper, King Edward, or Rooster. Waxy potatoes make gluey mash.
- Tip 2: Warm the milk before adding it. Cold milk seizes the potato starch and the mash turns gluey.
- Tip 3: Let the potatoes steam-dry after draining. Dry potatoes absorb butter better.
- Tip 4: Never use a food processor or blender – the blades break the starch and the mash turns to glue.
Scientific background
Floury potatoes have a high starch content and a low moisture content, which makes them ideal for mashing. When boiled and mashed, the starch granules swell and release their contents, creating a soft, creamy texture. Butter and warm milk coat the starch granules, preventing them from clumping and giving the mash its silky finish. White pepper is used instead of black pepper so that no dark specks appear in the finished mash.

FAQ
Why are my mashed potatoes gluey?
You probably used waxy potatoes, overcooked them, or added cold milk. Use floury potatoes, drain them well and warm the milk first.
What is the best potato for mash?
Floury potatoes like Maris Piper, King Edward or Rooster. They have a high starch content and give the silkiest mash.
Can I use a food processor?
No. A food processor will break down the potato starch and turn the mash into a sticky paste. Use a masher, a ricer, or a fork.
Can I make it in advance?
Yes. Make the mash as directed, cover with a lid and place over a pan of simmering water to keep warm for up to 30 minutes. Stir before serving.
WAGUU Petr advises: Cooking for 8 or more people?
8–12 people: Double the ingredients and use a larger pan, or cook in two batches. • 12+ people: Cook in two batches and keep the first batch warm over a pan of simmering water while you make the second.
Storage and reheating
Fridge: 3 days • Freezer: Not recommended • Reheating: In a pan over medium heat with a splash of milk, stirring gently. Or in a bowl covered with cling film in the microwave for 2 minutes.
