A pudding worth getting precise about

There are few things more satisfying to bring to the table than a chocolate fondant that behaves. Crack the top with the back of a spoon, and a dark, glossy ribbon of chocolate spills out across the plate. Get it wrong, and you have either a chocolate sponge or a puddle of raw batter. The difference is rarely the recipe — it is the timing, the tin, and a little bit of nerve.

This is restaurant cooking in the truest sense: simple ingredients, a short method, and one crucial variable you must control. Once you have made it two or three times, you will know your own oven well enough to nail it every single time.

What you need, and why each bit matters

For four puddings, you need: 100g unsalted butter, plus extra for greasing; 100g dark chocolate at 70% cocoa solids; 2 whole eggs and 2 extra yolks; 60g caster sugar; 1 tablespoon plain flour; a pinch of fine sea salt; and cocoa powder for dusting the moulds.

Chocolate choice genuinely changes the result. Anything below 60% cocoa will give a sweeter, thinner centre; above 75% and the fondant can turn slightly grainy and bitter. Supermarket own-brand 70% bars work beautifully — there is no need to hunt down anything expensive.

• Metal or ceramic ramekins — 175ml to 200ml, straight-sided. Thin metal conducts heat fast and gives a tighter molten centre; ceramic is more forgiving but needs an extra minute or so.
• An electric hand whisk for the eggs and sugar — a full five minutes of whisking by hand is tedious and inconsistent.
• A digital timer, not your phone's stopwatch buried in a pocket.
• A heavy baking tray, preheated with the oven. This is the single most underrated trick.

The batter: two minutes of folding

Melt the butter and chocolate together in a bowl set over barely simmering water, or in short bursts in the microwave. Let it cool for five minutes — hot chocolate mixture will scramble the eggs.

Whisk the two whole eggs, the two yolks and the caster sugar for a good five minutes until pale, thick and doubled in volume. The whisk should leave a trail that sits on the surface for a second before sinking. Fold in the chocolate mixture with a large metal spoon, then sift over the flour and salt and fold again, just until no streaks remain. Stop there. Overworking at this stage knocks out the air you have just spent five minutes adding.

Spoon into the buttered and cocoa-dusted moulds, filling them about two-thirds full. At this point the batter must rest. Cover with cling film and chill for at least 30 minutes, or up to 24 hours. Cold batter sets from the outside in, which is exactly how you get a firm wall around a liquid middle.

Baking: the eight-minute window

Heat the oven to 200°C fan, or 220°C conventional, with a heavy baking tray inside. Put the chilled moulds straight onto the hot tray and bake for 12 minutes — 13 if your ramekins are ceramic or your fridge is very cold. Do not open the door before 10 minutes.

What you are looking for: the tops should be set and slightly domed, with a faint wobble if you nudge the tray. The edges will have pulled away from the sides by a millimetre or two. If they look completely rigid, they are already overdone.

Leave them on the tray for exactly one minute, no longer, then run a thin knife around the edge and invert onto warm plates.

Serving, and a little seasonal flourish

Fondants wait for no one. Take them to the table the moment they are turned out, with a jug of cold double cream or a spoonful of clotted cream to pour into the molten centre. In late summer, a handful of lightly crushed raspberries or blackberries macerated in a teaspoon of caster sugar cuts the richness beautifully. From January, forced rhubarb poached in orange juice is the classic British pairing. In deep winter, a dusting of cocoa and a small glass of something dark and fortified is all you need.

If you are cooking for a crowd, bake in two batches rather than doubling up on trays — an overcrowded oven steams the puddings and you lose the contrast that makes them special.

When it goes wrong

• Collapsed into a puddle: underbaked or your oven runs cool. Add 90 seconds next time and check the oven with a thermometer — many domestic ovens are 15°C out.
• Solid all the way through: your batter was too warm, your ramekins too small, or you pushed past 14 minutes. Chill the batter properly and reduce the time.
• Stuck to the mould: the greasing was patchy. Butter thoroughly, dust with cocoa, and tap out the excess.
• Tough, rubbery texture: too much flour, or the eggs were overwhisked after the chocolate went in.

Make a note of your exact timing each time you bake these. Within three attempts you will have your own number written on the recipe card, and a pudding that never lets you down.
