Check the label to be sure they are genuine vanilla extract, and not imitation or "vanillin," which is artificial. Most extracts utilize an alcohol base; a few use water. There are a very few that contain vanillin, but stick to the pure products. And be sure to tell them you want a tasting party!

A fruit basket seems ordinary, unless it is full of well-selected exotic fruits. Foodies are actually fairly easy to please -- they love food!
