A short rest for just flour and water, before salt or levain join. It lets the flour hydrate fully and the gluten start developing on its own, so less mixing is needed later. Enzymes in the flour also begin breaking starch into sugars the fermentation will use. The result is a dough that's easier to shape, with better volume and a more open crumb.

Also known as tangzhong. A portion of flour and water, cooked together into a thick paste before joining the rest of the dough. Cooking it to around 65°C gelatinises the starch, so it holds far more water than raw flour would. That locked-in moisture is what keeps the bread soft and fresh for days, and lets us push hydration higher without the dough turning slack. We reach for kochstück when a loaf needs that extra softness and shelf life, without needing the bounce yudane gives.

Scalds flour with boiling water, usually in equal parts, then lets it cool and rest — often overnight. The heat gelatinises the starch on contact, and as it cools, that starch holds onto water the same way kochstück's cooked paste does. The rested paste turns firm and pliable, giving the crumb a soft, springy, almost mochi-like bounce. We reach for yudane specifically when that bounce is what a loaf needs — kochstück adds moisture alone; yudane adds moisture and texture together.

Cold slows the yeast down more than it slows the bacteria, so the bacteria get more time to shape the flavour — that's where the sourness and depth come from. The extra time also lets enzymes break proteins and starches down further. Cold dough is also firmer, easier to score cleanly. The result is a rounder, more complex flavour than a same-day loaf ever gets.

Using heat carefully to change something's structure, without overdoing it. For us, that means blooming whole spice briefly in hot fat before it joins anything else — a short burst of heat that releases oils that stay locked away in a raw spice otherwise. Handled gently, the aromatics spread evenly through the fat and carry through the whole dish. We choose tempering when we want a spice to be felt everywhere in something, rather than found in one place.

Toasting whole spice in a dry pan, with no fat involved. The heat draws the spice's oils to its own surface rather than releasing them into anything else, so the spice stays distinct rather than dispersing. Bite into one, and it's a burst — concentrated, separate from everything around it. We choose dry-roasting when we want a spice to be discovered rather than felt throughout, and we test a spice both ways before deciding which one earns a place in the final recipe.

Whey, the liquid left over from culturing butter, is reduced slowly with sugar rather than thrown away. As the water cooks off, the milk sugars caramelise into something dark and complex, while the whey's natural tang keeps it from tasting purely sweet. The result sits closer to a savoury caramel than a dessert one. We reach for whey caramel specifically when a sweet or butter wants an actual caramel note, not just more sweetness.

Made by fermenting oats with rice koji, the same mould used to ferment soy sauce and miso. As the koji breaks the oats' starch down into sugar, the result turns naturally sweet — without the alcohol or sourness yeast or bacterial fermentation would add. It carries a mild, faintly nutty flavour and a touch of umami, and a different kind of sweetness than honey gives. Used alongside honey rather than instead of it, the two round each other out into something neither gets to alone.

Once a ferment tastes right, it's brought to a boil with sugar. The heat stops the living culture immediately, while the sugar thickens the mixture and locks in that exact balance of flavour. The concentrated sugar also keeps it stable afterward. The result is a preserve fixed exactly where we wanted it.

Once a ferment tastes right, vinegar is added to stop it. The sudden drop in acidity shuts down the bacteria and wild yeast almost immediately. The vinegar also adds its own sharp edge on top of the fermented flavour underneath. The result is a pickle with two layers of acidity — the rounder fermented sourness, and the vinegar's brighter bite on top.

Alcohol stops a ferment the same way vinegar does — inhospitable to yeast and bacteria, so activity stops almost immediately. A gentle reduction afterward drives off the sharpest edge of the spirit while concentrating the flavour. Alcohol also holds onto aromatic compounds a straight heat-and-sugar stop tends to drive off. This is the method behind our richer, more spirit-forward preserves.

Spelt has a higher ratio of gliadin to glutenin than common wheat, needing real structural support to hold its shape. Baking in a tin rather than free-form gives it exactly that. The tin's walls hold the dough in as it rises and conduct heat quickly into the sides and base. Because the dough's own steam stays trapped inside, the crust comes out thin and soft rather than thick and blistered. The result is an even crumb and a loaf that slices cleanly.
