this is a super quick snack or light lunch - bread, then some good quality butter, then thinly sliced radishes, then a goodish sprinkling of a nice flaky salt. that's all you need for a rather elegant little repast.
i used a salt called murray river apricot salt, which is australian for fancy salt. it does sound fancy, but it isn't that expensive when you just use it for sprinkling on things. they have it online at lots of places and in austin i got it at central market and here in portland at zupan's. so it's around and all.
