About Buckwheat Flour
Not related to wheat — a gluten-free seed with a strong, earthy, slightly bitter flavour, essential to French galettes, soba noodles, and blini.
Why the Weight Per Cup Varies
Despite its coarser, irregular particles, buckwheat's starchy density gives it a cup weight of 120g — similar to wheat flour by coincidence, despite being a completely different, gluten-free product.
Names in Different Countries
Available as light (hulled, milder) or dark (unhulled, stronger) buckwheat flour.
Common Recipe Uses
Galettes, soba noodles, blini, partial addition (25–30%) to bread or cookies for flavour.
Substitutions
Not a 1:1 wheat substitute due to strong flavour and no gluten — use as a partial addition.
Frequently Asked Questions
Yes, naturally — despite the name, it is unrelated to wheat.
It contains flavonoids and tannins giving an earthy, slightly bitter taste — the defining character of soba and galettes.
Not directly — use it as a partial addition (up to 25–30%) or in recipes designed for it.
7.5g for a US/UK tablespoon, or 10g Australian.
