[Balthasar]

You know, we were taught that "cake" is uncountable.

[purplebug]

Cake is only uncountable when it's cut up. Then you'd say pieces of cake. But whole cakes are countable - "the baker made three cakes for the party."

Balthasar, here is some more food for thought.

Fruit or fruits ?

If you had pineapples, watermelons, bananas, oranges and strawberries at home, what would you say?

1. I have a lot of fruit at home. Right or wrong?
2. I have a lot of fruits at home. Right or wrong?
3. I have many fruit at home. Right or wrong?
4. I have many fruits at home. Right or wrong?
5. I have fruit at home. Right or wrong?
6. I have fruits at home. Right or wrong?

When you finish this think about the word "fish" too in the same context.

Cheers!
