Got it right, at last!

Berliner Landbrot -

70% Dove's Farm light rye

30% Bacheldre Organic Stoneground Strong White Flour

During his apprenticeship the baker Tom Roetz investigated the behaviour of machine-prepared rye preferments vs hand-prepared rye preferments using  a standard "Berliner Landbrot" formula.

My version of "Berliner Landbrot" is adapted from his paper, which is available online:

I tried to bake this bread several times with mixed sucess. Now I managed to get it just right for my taste:

A fairly open crumb, combined with a dark, caramelised crust.

Here the formula:

Preferment55510
Yield172.471600

Method:

Mix the preferment and leave it for about 14 hours at 28C. It should have a pleasant smell and taste.

Mix the preferment with the rest of the ingredients, the dough is easy to handle as it ought to be onthe stiffer side.

Knead for about 5 minutes, the dough wil become a bit smoother.

Rest the dough for 30 minutes at 28C

Shape with wet hands.

Proof for another 45 minutes at 28C.

I used bannetons this time, but this can also be baked freestanding or in tins.

Bake in a very hot oven  (Roetz says 290C!) for 10 minutes, then at 200C for about 50 minutes (750g loaves).

Things to watch out for

Temperature: During the preparation of this dough I managed to keep the dough temperature constant on 28C. 

Shaping: I did it quite gently this time, just gently forming a smooth roll with very wet hands.

Baking: My oven was as hot as it can be, with a new 3cm stone, and about 2 hours preheating (I did another bake just before)

Roetz used in his studies two decks: one heated to 290C for the first 10 minutes of the bake, and another one at 200C to finish the bake. I think it is most important for this bread to behin the bake hot.

My challenge now: to get these results consistently.

Happy Baking,

Juergen
