Thanks for the link! it was a lovely (and accurate) read. I'd like to add that in Finland you still get the round crispbreads with the hole in the middle. :) there re also other round flat rye breads with a hole that are less crispy - I used to eat those with butter and a Finnish havarti-like cheese. delicious. (unfortunately also chock full of gluten.)

I had never even considered using cucumber slices (or anything else) in place of crackers! Thanks for the tip, I will try it next time I find myself without any decent gf crackers :D
