I’m sorry, but I’m not sure what you mean by “joke” in your question. However, I can certainly explain the difference between jam and marmalade!
Below are the main Differences Between Jam and Marmalade Joke.
Jam and marmalade are both types of fruit spreads that are used as toppings for bread, toast, or pastries. The main difference between the two is the type of fruit used to make them.
Jam is made from crushed or pureed fruit, sugar, and pectin. Pectin is a naturally occurring substance that helps the jam to set and thicken. Jams can be made with a wide variety of fruits, such as strawberries, raspberries, blackberries, and apricots.
Marmalade, on the other hand, is made from citrus fruit, such as oranges, lemons, or grapefruits. Marmalade is made by boiling the fruit and then adding sugar and water to create a thick, sticky spread. Marmalade often has a slightly bitter taste due to the presence of the citrus rind.
So, to sum it up: jam can be made from a wide variety of fruits, while marmalade is made specifically from citrus fruits.
