Update: Just did a test run (have the final round of the competition on Monday), with meatballs encapsulating... Garlic confit (see, e.g. Recipe) Very delicious, tasty, and sweet with the burst of garlicky goodness... Texture slightly off-putting - the garlic was done in oil at 85c for 90 minutes and was soft and mushy, but we took whole cloves and embedded them in the meatballs, so they still had a slight firmness at the first bite to break the outer surface, and then turned into mush when you chewed... That would have been fine, but with the softness of the meatball, the sudden firm/squishy ball in the center came off more as a chewy overcooked bit of gristle or something. Deconstructed parmesan cheese (as noted above) Delicious, although maybe a bit subtle and overpowered by the meatball spices... However, the aftertaste was pure parmesan, for several seconds. Excellent. The gel held nicely at serving temp too. Smoked gouda Wonderful, and had the texture I was going for with the mozzarella initially - with the meatballs at 54c, the gouda was a molten ball of yum. The texture was amazing and unexpected, biting through the meatball shell. Flavor was good, but not as good as the above two. Gorgonzola Tried this as an oddball idea. The salty/sour flavor went nicely with the meatball, but it was quite non-traditional. I'd do it again, but maybe changing up from the oregano/thyme flavor. It was good, but I don't think it would win an Italian-specific combination. So, for the competition, I'm going to mush up the garlic confit into a paste and combine it with the parmesan gel, with a small ball of the combination in the center of each meatball. Wish me luck!
