Reconstructed as an unsoaked method; old beans may require another 5 min–10 min at high pressure. Keep charro beans brothy. They should not reduce to the texture of taco beans.

Recorded alternatives (no separate variation-specific testing observations were supplied):

  • Chorizo: Replace 100 g bacon with 150 g fresh chorizo.
  • Beer-braised: Replace 330 g water with 330 g lager.

Phase Outputs Used

Phase Output Use
Cooked charro beans Use cooked-charro-beans. Use all; approximately 1500 g is a source finished-weight estimate.

FAILURE MODES
