Marmalade is a very common blocker in Candy Crush Saga. It makes its first appearance in level 14. Marmalade is a translucent jelly type substance that covers a candy. Marmalade is broken by destroying adjacent candies to break the substance. If you match a candy combo with the same candy as whats under the marmalade, you will destroy the marmalade but not the candy underneath. You will have to match the candy again to break the candy that was under it. The marmalade is probably one of the easier blockers to destroy and is also one of the most common.
