Vollkornbrot in a tin: six failures and a very long bake

I spent most of last winter failing to make a decent Vollkornbrot and got it right somewhere around the middle of March. The method that finally worked is slower and duller than any of the ones that did not.

Stage 01Weigh out

Six loaves that did not work, described honestly

The first two were dense and wet in the middle with a gummy band an inch above the base, which is underbaking and nothing else. The third was baked long enough and came out dry and crumbly the whole way through, because I had overcorrected on water. The fourth collapsed in the tin about forty minutes into the bake, having been proved until it looked magnificent. The fifth tasted of very little. The sixth was close, and failed only because I cut it after two hours and watched the crumb smear along the blade.

Listing them out proved more useful than any single fix, because the pattern only appears once the failures are sitting next to each other on the page. Four of the six were timing problems at different ends of the process, one was hydration, and one was plain impatience. Not one of them was the recipe, which had never changed. A whole-grain rye loaf is mostly a schedule, and I had spent a winter treating it as a formula and blaming the ingredients.

Stage 02Work it

A soaker and a scald, and why I now do both

A soaker is cracked rye or coarse meal left in cold water overnight so that it is soft rather than gritty in the finished crumb. A scald is the same grain covered with water just off the boil, which gelatinises the starch and converts a little of it to sugar; it makes the loaf sweeter, darker and noticeably moister, and it keeps far better afterwards. For a long time I did one or the other and could never tell which was responsible for what, because I kept changing both between bakes.

Doing both, in separate bowls, settled the question in one weekend. The soaker goes on at nine in the evening with about two hundred grams of cracked rye and the same weight of cold water. The scald is a hundred and fifty grams of coarse whole rye under three hundred of near-boiling water, covered and left to cool overnight, and by morning it smells faintly of malt. Together they account for roughly a third of the total grain, and the loaf they make is a different object from the one without them.

Stage 03Watch it

The tin, the lid and three hours at low heat

The dough goes into a narrow tin lined with baking paper, pressed down firmly with a wet spoon so that no voids are left in the corners, levelled flat, and proved for about seventy minutes. Not ninety. The fourth failure taught me that a whole-grain rye proved until it looks impressive has nothing left to give in the oven and will simply sink. What I want is a surface that has only just begun to show fine cracks, which in this kitchen arrives somewhere between sixty-five and seventy-five minutes.

Then the lid goes on, or a sheet of foil crimped tightly over the rim, and the bake begins at two hundred and fifty for fifteen minutes before dropping in stages to a hundred and sixty for the remaining two and a half hours. Three hours in total, most of it at a temperature that barely browns anything at all. The lid keeps the crust soft enough to let the loaf expand through the first hour, and stops the top drying into a shell while the middle is still setting.

Stage 04Write it up

A day of waiting, and how it keeps

The loaf comes out of the tin immediately, gets wrapped in a clean cloth while it is still hot, and then sits for a full twenty-four hours before anybody comes near it with a knife. This is the step everybody skips, and it is the step that decides whether the crumb slices or behaves like paste. The starch needs that long to set properly. My sixth failure was nothing but a missing day, and it is the one I came closest to blaming on the recipe instead of on myself.

After the wait it cuts into thin dark slices that hold together, keeps for a week and a half in a cloth inside a tin, and is better on day four than it was on day one. It goes stale eventually rather than going mouldy, which is the other quiet advantage of all that acidity. I bake one most weeks between October and April and almost never in summer, when the kitchen is too warm for the fermentation and nobody in the flat wants a loaf this serious.
