Store tomatoes are not tomatoes. Unless you're buying somewhere legit and expensive af, the tomatoes you see in stores are picked green and gassed to turn red. They are dog shit. Probably worse, actually. Seek out local farms near you and get the good shit (and often cheaper than places like whole foods).

Tomatoes are one thing I never buy in a store, except sauce/canned tomatoes, as those products are derived from ripe tomatoes.
