Running low on strong flour? Here are the best verified substitutes, including how to adjust your measurements.

About strong flour
Strong flour is a wheat flour milled from hard wheat varieties with a high protein content, typically 11–13%. The elevated protein forms abundant gluten when hydrated and worked, giving doughs the strength and elasticity needed to trap gas and rise well. It is the foundation of most yeast-leavened breads, pizza bases, and pasta.
Best substitute
Plain flour has a lower protein content (9–11%) so the resulting dough will be softer and less elastic, producing a slightly denser crumb. It works adequately for simple yeasted loaves where a very chewy texture is not critical.
Alternative
Adding vital wheat gluten to plain flour raises the protein level to match strong flour, closely replicating its gluten structure and dough strength. Mix 1 tablespoon of vital wheat gluten into each cup of plain flour before measuring.

Alternative
Wholemeal bread flour is milled from whole wheat and retains a similarly high protein content to strong flour, though the bran particles can cut gluten strands slightly. It produces a denser, more robust loaf with a nuttier flavour.
Alternative
Spelt is an ancient grain with a moderate-to-high protein content, though its gluten is more fragile and extensible than that of modern wheat. Doughs made with spelt require gentler handling and shorter kneading times to avoid over-working the gluten.
Alternative
Semolina is coarsely milled durum wheat with very high protein and gluten content, making it excellent for pasta and some rustic breads. It produces a firmer, more golden result and absorbs liquid differently, so hydration adjustments are needed.
