Terrine is like a special type of cake made out of meat or vegetables. Just like cakes, terrine is baked in an oven but it's made up of different layers of ingredients.
So imagine a cake made up of different layers of meat, vegetable, or fish. Each layer gives the terrine a special taste that makes it extra delicious. Once it's baked, the layers become solid like a loaf of bread.
Terrine is usually served cold and it's cut into slices - just like how we cut cake slices. It's a special food that people like to make for parties and meals with friends and family.
