Armida had all sorts of tomatoes growing in her garden, and combined them with celery leaves to create earthy-sweet dishes. This frittata (a crustless Italian quiche) pays homage to these flavors, and to the prevalence of pecorino (sheep’s milk) cheese) in the hills of Lunigiana. To make the frittata, I slowly dry oiled, cut tomatoes; this is lovely to do under a hot summer sun, but is also easily accomplished in a low-temperature oven. The rich and sticky tomatoes are an integral part of the frittata, but also make for a delicious addition or garnish to many other dishes.
