I only did MM one time but wasn't at all impressed with its flavor - rather bland I thought. And when it comes to sauce making the small size requires too much peeling for me. I much prefer to use the larger plum and heart varieties for both better flavor and less work. ;-)

I also grew it one time as part of my late-blight resistance experiment. I also found the taste bland. Of course that year we didn’t get late blight so my experiment was pointless. I haven‘t grown many cocktail size tomatoes but Jaune Flamme has the most flavor out of the ones I’ve tried, although I wouldn’t call it sweet, more tart and complex.
