Thank you to all of you who recommended the hydroponic tomatoes produced by Mighty Vines in Rochelle IL.
My initial intent was to do an experiment and cook a ratatouille in the middle of winter with fresh vegetables: zucchini, eggplant, tomatoes, and of course onions and garlic.
I prepare this dish, which is one of my favorite ones (I lived in Provence and Languedoc where i was born for many years), very often every year from the end of July to October. Or as soon as the basic ingredients that I find at the Evanston farmers market are good enough to allow me to make a decently flavorful one. But I had never tried to cook one in winter. The major obstacle being the absence of good fresh tomatoes in Chicago. I had posted on the subject on LTH earlier this month because I had read an article somewhere on the web about these locally grown hydroponic tomatoes but could not remember their brand name. Thanks to LTH ers I bought some at Whole Foods in Evanston for $ 2.99 a pound, but back home found out that they were to small and not fleshy or juicy enough for a ratatouille. Besides, the zucchinis and eggplant I bought at WF were not satisfactory for my project. I have plenty of canned San Marzano Italian tomatoes in my pantry that I use all winter long, and even for some sauces in the summer, so tomatoes were in fact not the real problem.
So I decided to use my newly acquired Mighty Vine tomatoes to make a sauce that would top farfalle pasta, to accompany a simple Sunday night dinner of chicken thighs (bone in skin on). I browned the thighs in olive oil in a Le Creuset enameled cast iron pot, where I already have sauteed onions, then I added a few chopped San Marzano tomatoes, about 20 pitted black olives ( Kalamata) 3 cloves of chopped garlic, and some dry French rosé wine. Then I baked it in a 350 degree oven for 20 minutes.
In the meantime I had seeded the small and medium sized MV tomatoes and diced them small. I slowly sauteed them in olive oil in a stainless steel ``sauteuse`` (sauteing pan) with 3 cloves of garlic (roughly chopped), added salt and pepper and a touch of white wine , covered the pan with its glass lid, and gently cooked them for 20 minutes, crushing the remaining small chunks of tomatoes with a wooden spoon every 5 minutes, until I obtained a texture half-way between a sauce and a coulis. I was tempted to add some dry thyme but did not do it to save the original flavor of the tomatoes.
Believe me these Mighty Vine tomatoes were very tasty, even though for some of you this dish probably contains too much tomatoes and garlic. Not a problem for me.
