Can I use a slow cooker instead of a pressure cooker?
Yes, increase cooking time to 3–4 hours on low heat. The pressure cooker method is faster but both yield tender oxtail.
What brand of birria adobo sauce should I use?
Any jarred birria adobo sauce works; common brands include El Paso and Dona Maria. Taste and adjust seasoning as needed.
How do I know when the oxtail is tender enough?
After pressure cooking, the meat should shred easily with a fork and separate cleanly from the bone. If still tough, add 5 more minutes under pressure.
Can I make this ahead?
Yes, prepare up to 3 days in advance and refrigerate in an airtight container. Reheat gently on the stovetop or in the microwave before serving.
What is oxtail and where do I buy it?
Oxtail is beef tail, sold frozen or fresh at butcher counters and Latin/Asian markets. Thaw completely before cooking.
