Rugbrod

Ingredients

Equipment Needed

• •Loaf pan, approximately 30cm by 12cm
• •Large mixing bowl
• •Wooden spoon or sturdy spatula
• •Wire cooling rack
• •Sharp serrated bread knife

Instructions

1. 1

   Soak the grains and seeds

   Place the cracked rye berries, sunflower seeds, and flax seeds in a large mixing bowl. Pour the boiling water over them and stir once. The boiling water does two things: it begins to soften the hard cracked grains so they won't be gritty in the finished bread, and it activates the flax seeds, which will release a thick, sticky gel that helps hold the loaf together. Cover the bowl with a plate and leave it for thirty minutes, or until the mixture has cooled to warm.

   Don't skip the soaking. Unsoaked cracked rye stays hard through the bake and you'll feel it in every bite. Thirty minutes is the minimum. An hour is better.

   Mix the batter

   Add the dark rye flour, the sourdough starter, the remaining warm water, the salt, and the malt syrup to the soaked grains. Stir everything together with a strong wooden spoon or your hands until you have a heavy, wet batter. Not a dough. This is important. Rye has almost no gluten, so kneading does nothing except tire your arms. What rye needs is time and moisture. The mixture should be thick and sticky, like wet cement. If it feels too stiff to stir, add a splash more warm water. If it pours, you've added too much.

   The malt syrup deepens the color and adds a round, dark sweetness that balances the sour tang of the starter. If you can't find dark malt syrup, dark honey works, though the flavor will be slightly different.

   Fill the pan

   Grease a loaf pan generously with butter. Tip the batter in. It should fill the pan about two-thirds full. Smooth the top with a wet spatula. If you use a dry one, the batter will cling to it and fight you. Wet your hands and press the surface flat, then scatter a few extra sunflower seeds or flax seeds across the top if you like. This is not required, but it tells you at a glance which loaf is which if you bake more than one kind.

   Ferment overnight

   Cover the pan with a damp cloth and leave it somewhere warm overnight. The starter is doing the work now. Twelve hours, minimum. The wild yeast and the lactic acid bacteria are slowly fermenting the batter, producing the sour, complex flavor that makes rugbrod taste the way it does. No commercial yeast can replicate this. By morning, the surface will have cracked slightly and the batter will have risen just a little, maybe a centimetre or two. That's enough. Rugbrod doesn't rise like wheat bread. It stays dense and dark. That's the point.

   Look at the surface in the morning. If it has cracked, the starter has done its work. If there are no cracks and no rise at all, your starter may not be active enough. Give it another few hours in a warm spot before you bake.
5. 5

   Bake low and slow

   Heat the oven to 160C. Place the pan on the middle shelf and bake for one hour and forty-five minutes. The low temperature is deliberate. Rugbrod needs time in the oven for the cracked grains to finish cooking and for the starches to set. Too high and the crust burns before the centre is done. Too short and the centre stays gummy. After ninety minutes, check the loaf. It should sound hollow when you tap the top, and the crust should be deeply dark, almost mahogany. If the top is darkening too quickly, lay a piece of foil over it for the last twenty minutes.

   If you have an instant-read thermometer, the centre of the loaf should reach 98C. That tells you the starches have fully set and the interior won't be gummy when it cools.

   Cool completely before slicing

   Turn the loaf out of the pan onto a wire rack and let it cool completely. This is the hardest step and the most important. Do not slice this bread warm. I know the temptation. Resist it. Rugbrod continues to set as it cools. The interior, which is still slightly sticky and fragile when hot, firms into the dense, moist crumb that holds butter and toppings without crumbling. Cut it too early and it will be gummy and impossible to slice thinly. Wait at least four hours. Overnight is better. The flavor deepens as it rests. The joy of waiting is real with this bread.

Chef Tips

• •Use dark stone-ground rye flour. The coarse kind, not the fine pastry rye you find in some supermarkets. That coarseness is what gives rugbrod its texture and its character. If the flour feels silky between your fingers, it's too fine.
• •Your sourdough starter is everything. If it's sluggish, the bread will be flat and heavy without the sour depth that makes rugbrod taste right. Feed your starter the evening before you plan to mix the bread, and use it when it's at its most active, bubbly and slightly domed on top.
• •Rugbrod improves with time. It's good after four hours of cooling. It's better the next day. By the second day, the sour has settled and the flavors have deepened into something rounder and more complex. Don't eat it all on day one.
• •Slice it thin. Thinner than you think. Rugbrod is dense, and a thick slice overwhelms whatever you put on top. A sharp serrated knife and a steady hand are all you need. Let the knife do the work.

Advance Preparation

• •Rugbrod is a two-session bread. Mix the batter in the evening, bake in the morning. Plan accordingly. The total hands-on time is about twenty-five minutes spread across two days.
• •The baked loaf keeps for a full week wrapped tightly in a clean cloth or beeswax wrap at room temperature. It also freezes beautifully: slice it first, then freeze the slices flat so you can pull out exactly what you need. Toast frozen slices directly, no thawing required.
• •If you don't have an active rye sourdough starter, you'll need to begin one about five days before you bake. Mix equal parts dark rye flour and warm water in a jar, feed it daily with the same proportions, and by day five it should be bubbling and sour. That starter will last you years if you keep feeding it.
