Caldo de Res
Mexico's comforting beef and vegetable soup: bone-in shank simmered slowly with corn, carrots, potatoes, squash and cabbage, finished with lime and chile.
Method
Rinse the beef shank under cold water and put it in a 4 L pot with the water, half of the onion (in one piece), the peeled garlic, bay leaves, peppercorns and half of the salt. Bring to the boil on high heat; for the first 10 minutes keep skimming off the grey foam that rises so the broth stays clear. Turn down to low heat, set the lid slightly ajar and simmer gently for , until the meat is tender enough to pull apart with a fork.

high heat→low heatWhile the meat simmers, prepare the vegetables. Peel the carrot and cut it into 4 cm chunks; peel the potatoes and cut them in half (quarters if large). Cut the corn cob into 3–4 cm rounds with a heavy knife. Peel the chayote, remove the soft seed and cut it into wedges; cut the zucchini into 3 cm chunks. Cut the cabbage into wedges, leaving a little core on each so they hold together. For serving, finely chop the remaining onion, the cilantro and the chile, and cut the lime into wedges.
Lift out and discard the onion piece and bay leaves. Add the carrot, potatoes and corn, bring back to a gentle bubble on medium heat and cook for . If the broth no longer covers the vegetables, add a little hot water.

Cook's tip
Bone-in shank gives the broth body; boneless stewing beef works, but the broth is lighter. Once skimmed, never let it boil hard or the broth turns cloudy. It is even better the next day: chill, lift off the solid fat and reheat.
Cooking it at camp
For camping, simmer the meat at home the day before, cool it in its broth and carry it in a sealed container in a well-iced cooler. At camp, bring it to the boil in a large pot on the burner and cook the vegetables in it as in steps 3 and 4; warm the tortillas straight on the grill.
