Hi have just spoken to She Who Knows!!!!
A rissole is a mixture of chopped veg, meat ,other stuff. Bound with egg -- and patted into a flat round 3/4 inches across and 3/4inch deep. Suitable for frying or baking in the oven.
It could be called a PATTIE -- but not a pasty or pastry as they include a Pastry wrapover or base (as in Tart).
Therefore the clue is flawed and I should demand my money back.
Just back from 3rd gdaughters bthdy party at the Big house.
Also present an tame owl, fox, snake and Skunk. I was completely overshadowed.
Have a good week Thea(o)
