Culinary Arts

I recently tried a dish that a friend of mine made, consisting of vegetables and spices, which was completely covered in aluminum foil and cooked over a fire.  A simple recipe, but delicious and nutritious.  Is this art?  Does its simplicity keep it from being art?  Is it more likely to be art if my friend made up the recipe himself?  Or does the fact that its aesthetic value lies not in the way it looks or sounds, but in the way it tastes and smells, keep it from being art?  It was mentioned in class that the eyes and ears are more objective than the tongue, and that physical tastes are harder to gauge or judge (I forget the exact wording).  But what about acquired tastes? 

Having doubts

I don't know if I can do this.  I've been thinking about it since we talked about it on Monday, and I'm really not sure I can define art.  I realize I have another option, but I had already written a paragraph about how I define art prior to our class discussion.  It seems reasonably true, but I'm worried it's too inclusive.  I'm also worried that there are gaping holes in the logic that I can't or don't want to see.  So I read my paragraph and think about modifying it, taking into consideration what we came up with on Monday, but I'm a little short on space, and anyway, I don't see anywhere in my paragraph that I could open up to more thoughts/information. 
Question: Even if we have some of the pieces, some of the components that we can pretty much definitively say belong to art, is it better to just resist defining art?
