Choose tomatillos that are bright green, firm to the touch, and still in their papery husks—avoid any that are soft or yellowing, as they'll be overripe and less tangy.

Hold the poblano directly over a gas flame or under the broiler until blackened, then steam in a sealed bag for 5 minutes before peeling—this adds smoky complexity that raw peppers can't match.

Use short bursts on your food processor to maintain a chunky, textured salsa rather than creating a smooth paste—this preserves the fresh, rustic character that makes homemade salsa superior.

Taste your cilantro bunch before using—some batches have a soapy compound; if this is an issue for you, reduce the amount or substitute with fresh epazote or parsley for equally vibrant results.

Add lime juice just 15 minutes before serving rather than immediately—this prevents the acids from breaking down the tomatillos and keeps the salsa bright and crisp for maximum flavor impact.
