Tomatoes are a summer favorite and for good reason

Tomatoes are my favorite! This might sound heavy on the nostalgic side, but the smell of the stem and leaves sends me back to when I was 8 years old, running in my dad’s tomato fields behind our house. Acres and acres and rows and rows of ripe red tomatoes. My cousin and I would pick them right off the vine and eat them like apples. We may have even snuck a salt shaker out of the house and kept is stashed by the fence. It is a memory that is burned into my brain like it was yesterday.

I grow tomatoes in my own home garden now and will sometimes just go out there and rub my fingers through the leaves. The care-free days of summer all resurrectedby the smell of a tomato… man I need a life!
