Do Bay Leaves Make a Difference?

It's one of the cars, half between a hatchback and an estate. It does have a boot area, which in theory, you can't access from the main car. The only thing between you and it is a kind of slightly suede finished plastic. We put them in every, all these lasagnas, but I can't tell if it makes any difference. No one knows for sure, but no one's ever had the guts to not stick a bay leaf in early on.
