I don't like eggplant so I substituted other veggies.
Throwing all ingredients into a bowl without uniform sizing guarantees uneven cooking, as dense carrots refuse to soften while delicate zucchini turns to mush. When adapting this dish for smaller or larger portions, remember that surface-area-to-volume ratios change how trapped steam interacts with the produce inside the foil pouch. Mastering the dynamics of moisture release requires careful attention to both cutting geometry and thermal exposure.
Excess moisture is the primary enemy of good vegetable texture, releasing water that steams the ingredients rather than concentrating their natural sugars. Proper knife work ensures every single bite retains a distinct structure alongside a rich, savory coating.
