What can I use in place of Type 550 in the United Kingdom?
The recipe asks for Germany's Type 550. On a shelf in the United Kingdom the closest designation is strong white bread flour — close match. Below: the figures side by side, what changes in the bake, and the standards both come from.

The recipe calls for
Type 550Common wheat
Ash / mineral contentA roller mill not only cracks the grain, but also sorts the fragments and re-combines and re-grinds the separated fractions. This allows to control the amount of the outer layers vs inner parts of the grain that end up in the flour. Because the core of a grain is almost entirely made of starch, and the outer shell has almost all the minerals, this choice determines the mineral content of the finished product. This property of the flour is also called 'extraction': lower extraction means less of the outer shell is in the finished product.0.51–0.63 %fixed by the standardProteinProtein (both total mass and quality) are determined by the grain variety, the soil and the amount of nitrogen fertiliser. The mill cannot change this, but will blend different lots for product consistency. Protein content is mostly watched in wheat varieties, because of its relevance in bread making.10.0–12.0 %typical market range, not regulatedGrind / particle sizeWhen sorting the grain fragments, the mill can also control the particle size of the product.

What you might have to change
- About 1.5 pp more protein. Add 2–4 % more water and give the gluten a little longer to develop.
- United Kingdom: protein itself is not regulated, so two bags of the same designation can vary significantly. Read the nutrition panel for the actual number.
Practical implications of these numbers
Higher ash content More water absorbed, faster fermentation, more flavour. The bran particles can impair the gluten network. Mix gentler, ferment shorter.
Protein up More water needed, longer mixing, better gas retention and oven spring, chewier crumb. Wrong for sponge and shortcrust.
Grind coarser Slower hydration. The dough firms up over the first twenty minutes after mixing, as the water is absorbed.

The standards behind these figures
-
DE
Germany
- DIN 10355:2017-11 — Mahlerzeugnisse aus Getreide Mehl types for wheat, rye and spelt. Classifies Weizendunst and Weichweizengrieß but assigns them no type number. Paywalled: the Bavarian food authority defers to it rather than reproducing the bands, so the figures here are unverified.
-
UK
United Kingdom
- Bread and Flour Regulations 1998, Schedule 1 Fortification only — calcium carbonate 235–390 mg/100 g, iron at least 1.65, thiamin 0.24, nicotinic acid 1.60. No grades, type numbers, ash, protein or granulation are defined anywhere, so every UK band here is market practice.
