A friend of mine gave me two Better Boy F1 tomatoes (I had never tried them before).
The fruits were unexpectedly firm, but after cutting them open, I didn't feel like I was eating firm tomatoes. Anyway, the taste was excellent. I can see why people like it so much. Lots of tomato flavor. There was some sweetness.
I'm saving the F2 seeds from each fruit separately. The first fruit was larger.
