They make a really pretty display, don't they? I tasted them and all have different flavor profiles, acid, sugar, and "tomatoey-ness" are pretty distinct. The ones that look orange, in the bottom left, are my favorites. They are really varigated orange, red and yellow. These are going to be served with a side of a vinaigrette made with fresh basil oil and sherry vinegar. But I think I'm just going to have them with a pinch of fleur de sel.
I ended up using the basil oil to make a basil lemon mayonnaise to go with the tomatoes, and it was absolutely perfect with them (if I do say so myself). Put two egg yolks, juice and zest of one lemon, and a big pinch of salt in the blender, then dribble in about 1 cup of basil oil while the blender runs. Taste for seasoning. (The basil oil was one cup of loosely packed basil blended with about a cup of olive oil (not EVOO) and strained.)
