Eh, I just eat them

Hold the wing and bite out the 'pea'.

Never tried anything fancy with them. They're just something that crops up in season, like pollen rich alder cones......good for sooking, or hawthorn buds, nice for a wee bite of green stuff.
I do remember being told that Sycamore isn't native, it's an incomer like rabbits. Came in with the Romans or thereabouts and didn't take off, brought back in a millenia later and thrived.
Try a few different trees though, they're all different. Like acorns, or Rowans, some are fine as is, and others would dry paint :shudder:
Fred I would love to have a recipe
Wonder if Fergus the forager has done anything with them ?
cheers,
