A recipe calls for coating (slightly cooked) fennel bulbs in flour before roasting them, presumably to obtain a bit of a crust. Is there anything I could coat them with that is gluten-free?
@Nick is correct. Gram flour (milled from chickpeas) is used extensively for 'crunch' with fried stuff. It does have a taste of its own which although tasty, doesn't necessarily go with everything. But its definitely worth a try.
Its also a very good alternative to facial scrub cosmetics.
