The old Romans appreciated their lettuces and salads and crunchy vegetables even in poetry.
They knew their vinegars. They had eggs. Surely they had something that was mayonnaise or very like.
They had onions, celery and parsley -- you name it, they had it.
Except, they had no potatoes.
I do, and we have achieved a potato salad worthy of the gods, even if I am she who so deems the worthiness.
We have melon. We have ham. We have a green salad. We're ready for 90 degrees.
