💡 Tip: Buckwheat is naturally gluten-free despite the name (it's a seed, not wheat). The flavour is strong and earthy, so blend with milder flours for a softer taste.

Cooking with buckwheat flour
Despite the name, buckwheat is a seed rather than a wheat grain, so the flour is naturally gluten-free. It packs to about 120 g per cup and has a bold, earthy, almost grassy flavour — most bakers blend it half-and-half with a milder flour to soften the taste and lighten the texture. Light buckwheat flour is sifted of hulls and milder; dark (or wholemeal) buckwheat keeps more hull and tastes stronger.
It shines in French galettes, Japanese soba, Russian blini and pancakes, where its flavour is the point rather than something to hide.

How buckwheat flour compares with other flours & starches
120 g per cup places buckwheat flour in the middle of its category — lighter than self-rising flour (125 g) and heavier than '00' flour (116 g).
It weighs the same per cup as all-purpose flour (120 g), so those two swap one-for-one whether you measure by cup or by scale.
