As the other posters have mentioned, just go for a "mild" cheddar.

But there's a whole world of cheese out there! My wife thought that cheese didn't go much beyond the flat slices and tubes that you get in the Philippines. But now she's into all sorts and really enjoys the Christmas cheese board. She's not really into "blue" cheese yet though.

Instead of mild cheddar, you could go for Red Leicester or Double Gloucester. Both are very nice!
