Tea Time

Tea Time might make you think it’s another Battenberg puzzle, but no, this one is about sandwiches. Or Sandwich Sums.

I’ve decided that they’re tea sandwiches. Or tea Sandwich Sums? Let’s stick with tea sandwiches. Perhaps cucumber, or egg and cress, or egg salad.

I haven’t done sandwich puzzles before, and it turns out they’re fun!
