I hate to be that person who tries to convince someone to like something that they’ve emphatically declared that they dislike, however-
Have you tried overnight steel-cut oats in a slow cooker? Google Alton Brown’s recipe. You’ll find it on the Food Network website. Alton doesn’t steer people wrong, which is why I’m making an exception to my rule of not trying to convince someone that they might like something they claim to dislike.
(And if you try Brown’s recipe and still hate steel-cut oats, that’s fine.)
