A Cake Built for Damp Weather

There is a particular sort of British afternoon — the light gone flat by three o'clock, rain ticking against the window, the heating clicking on and off — that calls for something dark, sticky and generous. Ginger cake answers better than almost anything else. It is not a dainty cake. It is dense and moist, faintly medicinal in the best possible way, and it improves over the first few days rather than fading. Cut a thick slice, pour tea strong enough to stand a spoon in, and the afternoon sorts itself out.

The recipe below is the one I make from October through to March, though there is no rule against baking it in June. It uses both ground and fresh ginger, plus black treacle for that bitter, almost burnt-sugar depth that makes the whole thing taste older and wiser than it is. A slow oven does the rest.

What Goes In, and Why

Every ingredient here has a job. Black treacle is the backbone of the flavour, but it is fierce — too much and the cake turns bitter and heavy. Golden syrup softens it. Dark muscovado brings a fudgy, almost toffee note that ordinary caster sugar cannot manage.

• 225g plain flour, sifted with 1 tsp bicarbonate of soda, 2 tsp ground ginger, 1 tsp mixed spice, ½ tsp ground cinnamon and a good pinch of fine salt
• 115g unsalted butter, plus extra for greasing
• 115g dark muscovado sugar, bashed free of lumps
• 115g black treacle and 115g golden syrup — weigh them straight into the pan, don't faff with spoons
• 150ml whole milk, 2 large eggs, and 30g fresh root ginger, peeled and grated very finely

On the fresh ginger: grate it on the fine side of the box grater and use everything, juice and all. If you keep a knob of root ginger in the freezer, grate it from frozen — it turns to fluff and your fingers stay clean.

Mixing: Heat, Then Be Gentle

Set the oven to 150°C fan / 160°C conventional / gas mark 3. Grease a 900g (2lb) loaf tin and line it with a strip of baking parchment that runs up the two long sides — handles to lift it out later.

Put the butter, muscovado, treacle and golden syrup in a small pan over a low heat. Stir until everything has melted into a glossy dark liquid, then take it off the heat and let it cool for five minutes. Do not let it boil; boiling drives off the volatile notes in the treacle and you lose the very thing you are after.

In a jug, whisk the milk, eggs and grated fresh ginger together. Tip the dry ingredients into a large bowl, make a well in the middle, and pour in the warm treacle mixture. Stir, then add the milk mixture and whisk briefly until smooth. The batter will be distinctly thin — thinner than a Victoria sponge, closer to double cream. That is correct, and it is what gives you the moist crumb.

Pour it into the tin and give the tin a couple of sharp taps on the worktop to knock out large bubbles.

The Slow Oven and the Long Wait

Bake on the middle shelf for 50 to 60 minutes. Do not open the door before 45 minutes have passed, or the middle will sink and never quite recover. If your oven runs hot at the back, turn the tin around at the 45-minute mark.

The cake is ready when a skewer pushed into the centre comes out with a few moist crumbs clinging to it — not wet batter, not completely clean. A completely clean skewer usually means a dry cake two days later.

Leave it in the tin for 15 minutes, then lift it out by the parchment and cool on a rack. Now the important bit: wrap it while it is still faintly warm, first in baking parchment, then in foil, and leave it for a day or two before cutting. The treacle and the fresh ginger settle into each other, the crumb tightens and darkens, and the flavour deepens noticeably. A ginger cake eaten straight from the oven is fine. A ginger cake eaten on Thursday that was baked on Tuesday is something else entirely.

Serving, Keeping and Small Adjustments

Plain is best. If you want a finish, a thin lemon icing — icing sugar loosened with lemon juice, poured over and left to set — cuts through the treacle beautifully. A spoonful of thick cream or a slice of good mature Cheddar alongside is not a joke; it is a Yorkshire habit worth acquiring.

• To store: keep it wrapped in its parchment in a tin for up to five days. It genuinely improves for the first three.
• To freeze: slice it first, wrap individually, and freeze for up to three months. Thaw a slice at room temperature for an hour, or warm it briefly.
• If it sinks: usually underbaked or the oven door was opened early. Give it ten more minutes next time.
• If it tastes bitter: you have gone over on the treacle or baked it too long. Keep the treacle at 115g and trust the skewer.
• For a lighter version: swap 30g of the treacle for extra golden syrup, and add the finely grated zest of an orange with the fresh ginger.

Bake it on a grey afternoon, then leave it alone until another grey afternoon comes round. That is the whole trick.
