Trust me, they are delicious, they compliment the patoes really well. They are really sweet and flavorful. And if you don't like them they shouldn't affect the flavor of anything else in the pot.
Man, all this talk of corned beef. I need make some now. God I love that stuff.
Anyway, congratulations on the cooking thing, sounds like your first experience was quite satisfactory
P.S. I hope you shared with the cat
