For myself there are occasions that I don't know which Brocho to make on certain food.
For example rice cakes, crisps especially pringles, coated raisins, rolls when not eating them at a table and loads more.
I was thinking of organising the printing of a booklet or maybe a fridge magnet with a list of foods where it is NOT obvious what the Brocho is as an Ilui Neshomo.
