Zopf: The Swiss Sunday Braid

Every Sunday morning across the German-speaking cantons of Switzerland, kitchens fill with the smell of a baking zopf, and the whole country seems to slow down for it. The zopf is a braided milk-and-butter bread with a soft, close, faintly sweet crumb and a crust glazed to a deep, glossy mahogany, and it is as much a fixture of the Swiss weekend as a long walk and an even longer breakfast. My small change to the traditional loaf is to brown part of the butter before it goes into the dough, which threads a quiet toasted-nut warmth through the crumb and makes the crust taste as good as it looks.

Braided bread and the weight of Sunday

Zopf simply means “braid” or “plait” in German, and the bread takes its name from its shape. In some cantons it is called Züpfe; over the border in southern Germany the close relative is the Hefezopf. It is old, and it is bound up with ritual. One widely repeated tradition holds that the braid descends from an early-medieval Germanic mourning custom in which a widow would cut off her plait and lay it in her husband’s grave, later commuted to burying a braid of bread in her stead, a symbolic sacrifice. Whether or not that grim origin is literally true, the plaited-bread-as-offering idea is deep in central-European folk practice, and it explains why braided enriched breads cluster around Sundays, feast days and funerals.

By the nineteenth century the zopf had settled into its modern role as the Sunday and holiday bread of the Swiss table, richer than daily bread but far leaner than a cake, the sort of thing a household could justify once a week. It sits in the same great family of braided enriched breads as the Jewish six-strand challah, and the two are close enough that people often muddle them, though a good baker can taste the difference: challah is typically made with oil and no dairy so it stays pareve, and is often sweeter and more golden from a heavier egg content, while the zopf is built on milk and butter and is only just sweet, which lets the crust do the talking.

Butter, milk, and why the zopf is firmer than a brioche

The zopf occupies an interesting middle ground. It is enriched with butter, milk and egg, so it is soft and keeps well, yet it is a comparatively lean enrichment, roughly 60g of butter to 500g of flour, which is a fraction of what a brioche carries. That restraint is deliberate. A zopf needs to hold a crisp, defined braid through proving and baking, and a heavily buttered dough would slacken and blur the pattern. The firmer dough takes a sharp plait and keeps it.

Milk, rather than water, is what gives the crumb its tender, pale, almost cakey softness. The milk proteins and sugars (lactose) also help the crust brown and enrich the flavour. Browning part of the butter is my addition, and it works precisely because the base bread is so restrained: in a lean, milky dough a nutty background note has room to be noticed. Melt the rest of the butter unbrowned so you keep enough plain butteriness alongside the toasted flavour, and stir all of it into the milk so the fat is evenly dispersed before the flour goes in.

Because there is no sugar to speak of beyond the pinch that feeds the yeast, the deep colour of a zopf comes almost entirely from the egg-yolk glaze and the milk sugars. With so little dough sugar to caramelise, the glaze does the real work here. It is the crust.

Braiding the two-strand zopf

The classic Swiss shape is a two-strand braid, which sounds like a contradiction and is genuinely clever. You roll two ropes, lay them in a cross so you have four arms radiating from a centre, and then plait by folding opposing arms over one another in sequence, working from the centre out to the ends. The result is a plump, symmetrical braid that looks like a four-strand plait but is far easier to keep even. There are good step-by-step videos worth watching once; the movement is quicker to see than to describe.

Roll the ropes so they are fatter in the middle and taper towards the ends. This gives the finished braid an elegant, spindle-like profile that rises to a dome in the centre. Keep the braid reasonably tight but do not stretch the dough, which would tear the surface and cause the braid to open up as it proves. Tuck the ends firmly underneath so they do not spring loose in the oven.

If the two-strand plait defeats you the first time, a straightforward three-strand braid from three ropes works perfectly well and no Swiss grandmother will disown you. The two-strand version is simply the traditional and most handsome one.

The glaze, and getting that mahogany crust

Brush the proved braid with beaten egg yolk let down with a little milk, working the brush into every crevice so no pale gaps show after baking. For a truly deep, lacquered finish, give it a second coat: brush once, let the braid continue proving for ten minutes, then brush again just before it goes in. The double glaze builds a thicker layer of egg proteins and sugars that browns to a rich reddish-brown and shines. Take care not to let glaze pool in the crevices or on the tray, where it will scorch.

Bake until the crust is a properly deep mahogany and the base sounds hollow when tapped. A pale zopf is an under-baked, under-glazed one, and it is the most common way the bread disappoints. If your braid is colouring fast on top before the inside is done, tent it loosely with foil and keep baking; the centre wants to reach about 92C.

Tips, storage and variations

Make-ahead. Prove the dough, shape and braid it, then refrigerate the braid overnight covered. In the morning, let it come to room temperature and finish proving before glazing and baking, so a fresh zopf lands on the table without a dawn start.

Storage. A zopf keeps soft for two to three days wrapped in a cloth or tin. Slightly stale zopf makes exceptional French toast and even better bread-and-butter pudding, the milk-rich crumb soaking up custard beautifully.

Serving. The Swiss eat it simply: torn or sliced, with butter and jam or honey, and coffee. It is the natural centrepiece of a slow weekend spread, and it makes the finest breakfast toast, sitting somewhere between plain bread and the plusher tangzhong milk rolls.

Butterzopf and beyond. For a richer holiday loaf, push the butter to 80g and add a tablespoon of sugar. Some bakers work in raisins or lemon zest for feast days. Keep the dough firm enough to braid whatever you add.

Troubleshooting. A braid that splits or bursts open in the oven was under-proved, so the dough still had too much rise left and forced its way out through the weakest seam; give the second prove its full hour and slash nothing. A dense, tight crumb means under-kneading or a cold, sluggish first prove. And a dull, pale crust means the glaze was too thin or applied only once.

The zopf is a quiet bread, restrained where challah is generous and lean where brioche is lavish, and that restraint is exactly what makes it the perfect Sunday loaf: enough butter and milk to feel like a treat, enough backbone to hold a beautiful braid, and a crust that rewards the small extra effort of a double glaze. Brown a little of the butter, take your time over the plait, and give a Swiss weekend a try in your own kitchen.
