Well this is an interesting rabbit hole. I didn’t buy seed, I bought two plants at a local nursery. First of all I misspelled it, it is costoluto fiorentino. So I looked for seed on Google, came up with this. https://territorialseed.com/products/tomato-costoluto-fiorentino?variant=12786171478115¤cy=USD&utm_medium=product_sync&utm_source=google&utm_content=sag_organic&utm_campaign=sag_organic&srsltid=AfmBOorH5bN3MjbHXuryi_rivSGDqyTjxXQ5Hj4vMkexZSJpNjPh0tHqtTQ
Another thing. While ours looks like this on the inside, it is totally round no bumps and the stem is not recessed. When we pick the next one I’ll have to take a pic.
I’ve noticed that beefsteak tomatoes don’t always come out ribbed for me. Some are globe shaped. Even on a single plant. I have no idea what the causes might be.
Also gotta keep in mind that pics on the web aren’t going to be the same as real life. You’re looking at one tomato out of who knows how many that looked good to upload.
Seed companies, especially Baker Creek are guilty of that.
Sure, you can put $20(not including labor) of care into a single plant and get something amazing but are you trying to growing food, trying to win a prize at the fair or trying to sell seeds?
