I found a recipe for these blue cheese and walnut biscuits in December issue of Pereköök, a monthly recipe booklet of Estonian family journal Pere ja Kodu. They were really simple to make and delicious, and went very well with glög/mulled wine:) These are a lovely addition to my cheesy feet biscuits.
Blue cheese and walnut biscuits
150 grams butter
300 ml plain flour
0.5 tsp salt
100-150 grams blue cheese
50 grams chopped walnuts
Chop butter, flour and salt into crumbs, add chopped blue cheese and mix into a dough (if the dough feels to greasy, add a bit more flour).
Add the nuts, knead a bit and form into 2 rolls (3 cm diameter). Wrap into a clingfilm and put into a fridge for at least an hour.
Cut each roll into 5 mm discs and put these onto a baking tray. Bake at 175˚C for 12-15 minutes, until they are light golden (do NOT let them go brown, as cheese goes bitter).
These biscuits keep for a week in an airtight container (in theory. We finished them straight away).
