Everything Can Change. Except the Potatoes.

I have always believed the roast potato is not to be messed with. There is something almost holy about a properly made one — crisp at the edges, soft through the middle, unapologetically simple. It asks for nothing beyond salt, and it is, in its way, perfectly English: understated, reliable, entirely itself.

So it was a small comfort to discover I'm not alone in this. A recent survey of Sunday roast habits found that whatever else diners are willing to reinvent on the plate, the roast potatoes remain almost universally off-limits. A fair number of people, it turns out, have added ketchup to a roast dinner in the past year, and I'm told — with a straight face — that hot sauce, chilli oil, and even kimchi have made appearances. Younger diners are the most willing to experiment. I read it and winced.

Buried in the same survey, though, was the detail that mattered more: however far people are willing to go with everything else, the potatoes stay sacred.

I find that oddly reassuring. Not because I think kimchi belongs anywhere near a roast — I remain unconvinced — but because it means the experimenting isn't chaos. It's a negotiation, and a fairly orderly one. Nobody sat down and agreed on the rules. The table worked it out on its own: reinvent freely, but leave the potatoes alone.

If you're the one hosting a table that spans generations — which most of us are, eventually — the useful question isn't whether to allow this. It's how to host it without the meal turning into a free-for-all, and without your own eyebrows giving you away at the table.

A few things I've learned:

Decide what's sacred before the table is set, not during. Pick the one or two dishes you're not willing to see altered — the ones that took you years to get right, or that carry weight beyond the food itself. Those go out as they are, no negotiation offered. Everything else can flex.

Keep condiments out of sight, not on the table at all. Ketchup and hot sauce sitting next to the gravy boat reads as an invitation before anyone's even asked. Keep them in the kitchen instead, and bring them out only if someone actually requests them. It changes the entire tone of the request — from “help yourself” to “if you really must.”

Say the quiet rule out loud, once, lightly. “Potatoes are non-negotiable, everything else is fair game” takes the tension out of it before it starts, and spares you having to enforce it with a look.

Let the youngest diners customise first. Once a child has ketchup on their plate, nobody else has to feel self-conscious asking. It also means the dish that took the longest to make isn't the one being tinkered with at the table.

None of this requires a conversation at the table. Just a few decisions made in advance.

Here is my version of the perfect roast potato.

Crispy Roast Potatoes

Ingredients

• Potatoes, peeled (allow roughly 200g per person)
• Extra virgin olive oil, a generous amount for the base of the roasting dish
• 2 garlic cloves
• 2 sprigs parsley
• Coarse salt
• Black pepper, milled

Method

1. Boil the peeled potatoes in salted water for about 10 minutes, until just slightly soft — a knife should meet a little resistance.
2. While they boil, pour the olive oil into a Pyrex dish with the garlic cloves and parsley. Place in the oven at 180°C to let the oil take on the flavour.
3. Once the potatoes are soft, strain and return them to the pan. Cover with the lid and shake firmly — enough to rough up the edges and mush the corners slightly. This is what gives the crunch later.
4. Pour the potatoes carefully into the hot oil (it may sputter), then roll them so every side is coated.
5. Sprinkle with coarse salt and a mill of pepper.
6. Roast for approximately 45 minutes, until crisp on the outside and soft in the middle.

A Note from Mrs H

Always use excellent extra virgin olive oil. It makes all the difference.
