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.
