Broiling tomatillos requires precise visual cues to prevent bitter flavors. Position the cookie sheet within four inches of the heating element. Watch for large black blisters to form on the skins. Shake the pan halfway through the eight-minute cooking window to ensure even heat distribution. Undercooked fruit tastes watery and sharp. Overcooked fruit yields a muddy, bitter puree.
Tomatillos contain high levels of citric and malic acids. These organic acids interact chemically with the capsaicin present in habanero, jalapeno, and serrano peppers. Roasting degrades some of these harsh acids while concentrating natural sugars. Blending the charred vegetables immediately releases pectin, which thickens the final sauce naturally without added starches.
