- Do I need to rinse corned beef before cooking?
Yep! Give your corned beef a quick rinse under cool water before tossing it in the slow cooker. This helps wash away some of the extra salt so it’s not overly salty when cooked.
- What if my corned beef doesn’t come with a spice packet?
No spice packet? No problem! You can make your own by tossing in some whole peppercorns, bay leaves, mustard seeds, coriander seeds, and cloves. Super easy, and gives all that classic flavor.
- When should I add the cabbage?
Add the cabbage wedges about 1 hour and 20 minutes before the end of cooking if you’re on high. If you’re cooking on low, add them about 2 hours before it’s done. This way, the cabbage will be tender but not mushy.
- Can I use beer instead of water for more flavor?
Absolutely! Swap out some or all of the water for a good stout or ale if you want to give your corned beef a deeper, richer flavor. Guinness is a popular choice — but any dark beer works!
- How do I slice corned beef so it’s tender?
Here’s the trick: let it rest for about 5-10 minutes after cooking, then slice against the grain. This makes sure every piece is super tender and easy to eat.
