Well, guilty, it's indeed the 50mm /1.8...

I used the largest aperture possible, because the background was so messy it as better in a large blur...
Anyway, given the distance I wanted for the right composition, to have half of the tomato in focus (the half closest to the lens, as we don't see through it), it makes about 3cm, as it' a big tomato. The handy DOF calculator on my phone told me I would have to use f/11, so bye bye the blurry background. Using my 250mm zoom at f/11 would have been about the same, but at 2 meters and with virtually no perspective...
So I went with the 50mm @f/1.8, and made sure with the magnified manual focus in live view that the droplets in the highlights were sharp (this decision took about 20 seconds).
