As a kid, during the summer, I remember riding with my Dad on day trips. Most of these trips were for hours at a time. I have the most vivid memory of us enjoying lunch out of his black Stanley lunch box. My Mom would pack homemade tacos, carefully stacked and wrapped in foil paper and a kitchen towel to keep them warm. The story behind the tacos de canasta, also known as tacos sudados, years back the women in Mexico, would prepare assorted tacos stacked in a basket that was lined with a plastic bag and paper, then covered to keep them warm. Many times they would have to travel for a distance before selling these wonderful homemade tacos. The tacos were usually filled with potatoes or beans, foods that could hold up at room temperature for long periods of time.

Resting the cooked tacos under a kitchen towel for ten minutes is the single action that transforms crisp tortillas into tender, pliable street-style tacos sudados. Without this trapped residual heat and moisture, the corn wrappers remain stiff and crack upon folding. Traditional vendors use lined baskets to retain this warmth, creating a gentle steam environment that softens the exterior while melting the interior jack cheese.
Success relies heavily on how you handle the dried and fresh capsicums. Broiling the poblano pepper for five to six minutes per side until the skin blisters makes it possible to peel away the bitter outer layer easily. Meanwhile, microwaving the guajillo peppers in water for six to eight minutes rehydrates their tough flesh rapidly, ensuring the blender can pulverize them into a completely smooth braising liquid without fibrous chunks.
Using dried guajillos yields a concentrated, earthy background flavor with deep color, whereas fresh red chiles would introduce brighter, more vegetal notes and higher water content that extends the reduction time.
