Dinner Hall Days: The Canteen Classics Worth Cooking Again

There is a particular smell that hits you outside a school canteen at twenty past twelve: hot metal, boiled carrots, washing-up liquid and, if you were lucky, something sweet baking in a tray. I did not appreciate it at the time. I was too busy negotiating a plastic chair and wondering whether the dinner ladies would notice if I swapped my apple for a second chocolate concrete. But memory is a strange seasoning. Give it thirty years and even the lumpy custard starts to look like comfort.

This is not a plea to bring back every soggy chip and grey mince mound. Some school dinners deserved their reputation. But a handful of canteen classics — pink custard, chocolate concrete, gypsy tart — were genuinely good in their own wonky way. They were cheap, filling and unfussy. And with a bit of care at home, they still are.

The pink custard principle

Pink custard is less a recipe than a mood. In the dinner hall it arrived in a pale pink puddle, sometimes with skin, sometimes without, always tasting faintly of strawberries and mostly of vanilla. It was poured over sponge, crumble or a slab of chocolate concrete and made everything feel like a treat.

At home, start with a proper custard. Warm 500ml whole milk with a split vanilla pod or a teaspoon of vanilla paste. Whisk four egg yolks with 60g caster sugar until pale, then pour in the hot milk slowly, stirring all the time. Return to the pan and cook gently until it coats the back of a spoon. Take it off the heat before it turns scrambled. For the pink, stir in a tablespoon of raspberry jam pushed through a sieve, or a little freeze-dried strawberry powder. A drop of pink food colouring is allowed if you are feeling authentic rather than purist.

The result is not neon. It is soft, vanilla-heavy and gently fruity — which is probably what the dinner ladies were aiming for before the food budget got involved.

Chocolate concrete and the art of the traybake

Chocolate concrete — also called chocolate crunch, chocolate cracknel or, in some parts of the country, simply 'that hard chocolate stuff' — was the school pudding that doubled as a dental test. It was baked in a big shallow tray, cut into rectangles and served with custard or, on special days, a scoop of ice cream.

The home version is easy and much kinder to fillings. Rub 175g cold butter into 250g plain flour, 100g caster sugar and 40g cocoa powder until it looks like damp sand. Press it into a lined tin — roughly 20cm by 30cm — and bake at 180C for about 25 minutes. It should be firm at the edges and just set in the middle. Score it into squares while warm, then leave it to cool completely before cutting. The texture is the point: crisp, sandy, deeply chocolatey and made for dunking.

You can add a handful of oats or a spoon of golden syrup if you want a softer bite, but the classic is unapologetically plain. Serve it warm with cold custard, or cold with hot custard. Both are correct.

Gypsy tart: the Kentish canteen legend

Gypsy tart is the one that sounds made up until you meet it. A pastry case filled with a thick, caramel-coloured custard made from evaporated milk and brown sugar, it is a Kentish school dinner legend and a masterclass in doing a lot with very little.

Whisk a 400g tin of evaporated milk with 200g dark muscovado sugar for ten to fifteen minutes — an electric whisk is your friend — until the sugar has dissolved and the mixture has thickened and lightened slightly. Pour it into a blind-baked 23cm pastry case and bake at 200C for about ten minutes, until just set with a slight wobble. Cool completely before slicing. It is sweet, slightly smoky and dangerously easy to eat.

The first time you make it, you will think you have done something wrong because the filling looks so simple. The second time, you will make two.

The turkey twizzler problem

We cannot talk about school dinners without mentioning the turkey twizzler. It was pink, spiralled, vaguely meat-adjacent and beloved by a generation of children who did not read the ingredients. Then came the campaign, the documentary, the headlines and the great canteen clear-out. The twizzler became a symbol of everything wrong with processed school food, and it quietly disappeared from most menus.

I am not here to defend the industrial twizzler. But I am interested in what its absence took with it: a certain kind of shameless, salty, handheld pleasure that children actually wanted to eat. The lesson is not that we should bring back extruded turkey. It is that school food has to be both nutritious and liked. A canteen that serves nothing but lentil bake and steamed broccoli is not a triumph if the children bin it and eat crisps on the bus home.

Why the dinner hall emptied

School dinners did not vanish in one go. They were slowly squeezed by tight budgets, competitive tendering, new nutritional standards and the rise of the packed lunch. The old canteen classics were labour-intensive and old-fashioned. Pink custard needs someone to whisk it. Gypsy tart needs someone to blind-bake pastry. Chocolate concrete needs someone to cut it into neat rectangles before the bell.

By the time I was in secondary school, the dinner hall had become a cash cafeteria with chips, paninis and a salad bar that nobody touched. The puddings were pre-packed. The trays were still there, but the ritual had gone.

Bringing it back without the tray

The good news is that these dishes belong in a home kitchen. They are cheap, forgiving and deeply unfashionable in the best way. A gypsy tart costs pennies and feeds eight. Chocolate concrete is a traybake you can make after work. Pink custard turns a plain sponge into an event.

My suggestion is a canteen supper, once in a while. Make a simple roast chicken or a jacket potato, then serve a slab of chocolate concrete with pink custard for pudding. Put the custard in a jug. Let people pour their own. It will not taste exactly like school — the milk will be better, the vanilla will be real — but the feeling will be there.

And that is the point. We do not need to recreate the dinner hall exactly. We just need to remember why some of it made us happy, and cook those bits with a little more love.
