In this video, Internet Shaquille explains why even downmarket restaurant burritos beat your homemade ones. In brief:
• Supermarket-brand tortillas are too small and thick.
• You fail to warm your tortilla first, or you overcook it.
• Your fold is wrong or insufficiently tight.
• You fail to sear the seam to seal it shut.
• You fail to wrap the finished burrito in thin foil.
