There are certain sprays used at least a week before harvest. I can't recall the specific name offhand (I'll look into it). If a tomato tastes chemical, bitter, or just plain wrong, toss it immediately. It usually means it was harvested too soon after spraying and hasn't cleared the mandatory waiting period.
So, what does a healthy tomato actually look like? A real one should have a potent aroma—especially near the stem. You just can't fake that natural scent. When you slice it open, the flesh shouldn't be spongy or leave a bad taste in your mouth.
Thanks for the detailed breakdown and the solid advice.
