The Mess Factor – Washing ground beef can create a mess, with grease splashing everywhere. Also, dumping fats down the drain can cause clogs when the grease solidifies, leading to expensive plumbing fixes. A smarter option is to let the fat cool and harden before discarding it in the trash. In the end, whether to rinse ground beef or not is up to personal preference. Weigh the pros and cons. The next time you cook, go with the method that fits your taste and texture needs. Enjoy your cooking
