One of my undiagnosed passions is for inexpensive fried fish sandwiches. These days the cheap fish piece is pollock. My local supermarket has these fish sandwiches available at what I took to be odd times of the year.
Turns out it was for Lent. Oh ignoramus me! But the delicious patties have been hit and miss these days even in their season. For every three trips to find them I've had two failures. The Deli cooks seem to be ill informed as to the 'reason for the season' and their availability.
